A question on newborn sewing patterns

Pam had this question

Supposedly the XXS size on commercial patterns (McCalls, Simplicity, 
Butterick) is supposed to be for babies 7 lbs or less, but they swallow 
newborns up.  If you read around the Internet, there are lots of frustrated 
grandmothers and mothers-to-be that want to sew for their new or expected  baby, but can't find a pattern that will fit.  I read that doll clothing  patterns don't work because the neck is wrong for a human infant. I tried buying vintage layette patterns from Etsy and they were just as bad.  I  want to know how to downsize a commercial XXS dress or romper pattern so it fits a NEW 7-8 lb baby.

I had similar challenges sewing an infant shirt from a Butterick pattern. You are right that the sizing is just not right. You are also right that doll clothing patterns are not proportionally correct either.

There really is no easy way to fix the sizing issue. Perhaps the easiest would be to fold out some of the extra width and length to make the pattern smaller? Maybe try grading the pattern smaller -- though that won't solve the other problems that probably exist in your pattern. I can't really tell you how much to reduce the pattern because I don't know what pattern you are using. Even then, it would hard to advise you because I ended up redrafting the pattern I used above to even get it to work right.

One suggestion is to go to a thrift store and buy clothing in the size you want, take it apart and trace it off. Don't forget to add in proper seam allowances - as the existing seams have probably been trimmed off.

Some more grading questions

I received some more grading questions.

Grading by Pattern Shifting

I am wondering what you think of the section in Aldrich's book about grading?  It seems like a simplified method in some ways and so I am wondering if for someone simply making the patterns (instead of the clothes) might this method do just fine?

 There are different approaches to grading. Aldrich's "method" is similar to Handford, just presented in a different way. The movements of the pattern pieces is done in basically the same way as Handford. I have not graded a pattern using Aldrich's method, but I don't see that it would be a problem. Just keep in mind that her grade rules are based off her own sizing study of a British demographic. It may or may not work for your customer profile.

DIY or hire a pattern grader

Its not that I am adverse to putting in the extra time, but sometimes I wonder to myself if I am doing way more work than necessary in order to avoid "cutting corners" and making a product that in the end is below par.

I've been grading patterns for over 15 years. I'm still learning. If you want a superior product, you will have to spend the time learning how it's done and gain necessary experience. People in business either hire someone to fill a knowledge or time gap or they spend a lot of time learning in the school of hard knocks. Grading is not especially difficult, but it does take time and effort to learn it. The best way to learn is by trying and doing. I don't mean to sound harsh, but there is no magic book or trick that will help you get what you want faster.

Can I grade patterns with Adobe Illustrator?

I am not drafting/grading using a cad program but am doing all my work by hand and in Adobe Illustrator if that helps you answer my question better.

A lot of people ask me if they can use Adobe Illustrator for pattern making and grading. I suppose you could but to be honest, it's not for the faint of heart. I know there are indie pattern makers using Illustrator to do what you describe. But as a professional pattern maker and grader, Illustrator does not provide the level of accuracy and control that is needed for superior results. If given a choice, I would do all of my pattern making and grading by hand, or in other words with a pencil and paper.

Now there are pattern companies that draft their patterns either in CAD or scan in hand drafted patterns and add all the extra notations in Illustrator. The Big 4 do it that way. No problems there.

Designing and grading for a large size range

I get the following question from time to time:

I am a self taught pattern drafter, drafting patterns for myself and my 
kids for years.  I decided to turn this into a business recently and am 
creating a line of children's patterns for the home sewer.  My size range 
is 6m-10 and this is where my question is... Can you help me understand the process of redrafting the SAME style/pattern in my different base sizes?  I  get that I can't just take a size 5 and grade all the other sizes from 
there.  I own several popular pattern drafting books as well as 2 different 
grading books and I can't seem to find this information anywhere.  Any 
information you can provide me would be SO HELPFUL.  I am guessing there is some precise way to redraft my base sizes so the design doesn't change much.  Can you shed some light on how they do this in the business?  THANK YOU!

There are several things. First, it is not unusual when designing children's clothing to cover a large size range. The reality is it is much more work than you would think. I would recommend reviewing my previous blog entries on grading, especially Creating a Grading Standard (also read the other grading tutorials, they'll be helpful).

Unfortunately, there is no other precise way to redraft your sample or base sizes except good old-fashioned pattern drafting. If you have some basic pattern blocks for each size range, then it is no big deal. Just starting out, though, it is a lot of work. It will take less time and become easier over time, so no worries. One thing to pay attention to are proportions. You may need to alter the design to accommodate the size while still giving the impression of the same overall design idea.

Grading a skirt pattern

I sewed a skirt from a Burda pattern 2 years ago in desperation. I had gained weight and none of my skirts fit me anymore. 6 months later, I dropped all that weight and the skirt was simply too big. I liked the skirt pattern and it fit really well, but I had to grade the skirt pattern down in order to use it again.

In order to grade the skirt, I had to figure out the grade for Burda's patterns. I did this by looking at their measurement charts and comparing the sizes. With a little math I determined that Burda was using a 1.5 inch grade in the waist and hips. After comparing my measurements with the chart, I learned I only needed to go down one size.

So I pulled out my handy Jack Handford grading book and followed the instructions for grading a woman's skirt one size down. There are charts and instructions for a 1, 1.5, and 2 inch grade. It was so much easier to do than I expected. I knocked this out pretty quick. This book is now out of print, but if you can find it, buy it.

And I may be too much of a nerd, but I assigned a style number and created my own cutting spec for future reference. Now all I have to decide is which fabric to use to make up my next skirt.

T-shirt pattern quest pt. 6 : How to correct the fit of the armhole of a fitted t-shirt

I created some drawings to further explain the armhole problem on my t-shirt pattern. Nearly all drafting instructions that I've seen for t-shirts are pretty much the same. First you enlarge the armhole and drop the shoulder. Then the front and back bodice are traced off with identical bodice shaping and armhole shaping. The only difference might be the neck. If you lay the pattern pieces on top of each other, you will get something like this.

This kind of pattern works ok for a boxy, loose fitting t-shirt. If you want a more fitted t-shirt, then it simply won't work. In my case, the symmetrical armholes caused the front of the shirt to be pulled toward the back. The closer the fit, the less symmetry in general. When you look at the human body, you can see there is no symmetry between the front and back so patterns should reflect this. (Most people are not truly symmetrical left to right either). Children generally are more symmetrical than adults and the patterns for them reflect this. But, even there, the more fitted the style, the less symmetry though the differences are smaller. Anyway, the patterns above resulted in a fit that looked like below. The red arrows help emphasize the shape and length differences of the front and back armholes.

To correct this problem, I needed to lengthen the back armhole. I compared the armhole of my blouse pattern, which was not symmetrical, to the t-shirt armhole to determine how much longer it should be. Slash and spread and the pattern should look like something below.

 With a result that looks much improved.

The next thing on my list is to make adjustments for front versus back body width.

T-shirt pattern quest pt. 5 : Evaluating the fit of the armhole

I sewed up two more samples of my t-shirt pattern. I was still not satisfied with the fit. There were wrinkles around the armhole and elsewhere. I spent a bit of time studying the pictures below to try understand the fitting problem and how to solve it.

It finally occurred to me why the armhole was giving me so many problems. The back armhole was too short. You can actually see in the picture that the front of the t-shirt is being pulled toward the back at the shoulder seam and underarm. The fix was rather simple - make the back armhole longer.

What a difference, don't you think? There are some other fit problems. I'm still debating the amount that I scooped out on the front armhole. I think I may need some extra width across the front. And then there is the sleeve that wants to twist. But overall, this is pretty good and those complaints are minor. Will there be a version 5.0? Probably.

Book Review : Sew Serendipity

There seems to be a trend in new sewing books for the home sewing market. Some are written by fabric or textile surface designers as a way to expand their personal brand, others are written by indie pattern makers. Usually, they include basic how-to sew information and patterns. My local library received two of the Sew Serendipity sewing books written by Kay Whitt, an indie pattern maker (though she does sell to McCall's). The first book I brought home was the book featuring skirts and coats.

The book is organized with basic sewing how-to first followed by common instructions on how to sew the designs featured in the book. Finally, the designs are featured with beautiful photography. I have to admit I skimmed most of the how-to sewing instruction as I am probably a bit more advanced. There are some photo step-by-step instructions and each design has additional illustrated step-by-step instructions. A beginning sewist would have to flip back and forth several times to get complete instructions.

There are three basic designs, a skirt, a tunic/dress, and two jackets. Variations are presented for each design with changes in embellishment, design details, and fabric prints while the basic pattern pieces do not change. I do like the basic shapes of the styles presented, though some of the design details are just not my taste. The patterns are sized XXS to XXL and her measurement chart seems to follow a regular grade, which is nice.

As a pattern maker, I was very pleased when looking at the actual pattern pieces. The line width used on the pattern pieces is very fine, which is so much better than the Big 4. Also, the notches were not the traditional outward V notches but rather slit style notches. I did trace off the tunic pattern and walked some of the pattern pieces and they matched up really well. It is important to read the pattern sheet carefully because there are not a lot of markings other than notches and the piece name. Seam allowances are 1/2 inch unless otherwise noted. In addition, you have to read the instructions for the selected design and the basic how-to for the section. As an example, there is no sleeve cuff pattern piece because it is just a rectangle, but the dimensions are given in the basic how-to section.

A few of the seams needed a bit of refinement, but should not bother most home sewists. One area that will probably cause difficulty is the coat facing. I recommend redrawing the outer facing edge just to make it easier to sew. I think the facing has a sharp inward corner to make it easier when topstitching the facing down, so the facing shape is probably intentional. As an option you can use some other guide while topstitching and still smooth out that shape to make it easier to edge finish. Just my personal preference.

Overall, the book has a nice presentation and the designs are generally appealing. As I mentioned, I did trace off the tunic blouse to sew up but I have to put it off until I get a zipper. So the review is a bit incomplete but I think a beginning sewist will enjoy it.
