As part of finishing up my pattern blocks, I needed to add the armhole notches. Double notches for the back and single for the front. The front and back notches are a different distant from the side seam rather than symmetric. This helps ensure that the front sleeve matches the front armhole and vice-versa. The notches indicate nothing other than front and back.
This is my original sleeve from blouse 1.0 and 2.0. This sleeve can be used as the basis for any future variation. The original blouse has an elastic casing, so I noted the details related to that on the pattern piece.
I also finally got around to making the buttonhole guide. My awl from my book making helped make the holes in the tag board, but really any basic awl will work.
Further pattern making work:
1. Redo collar band shaping - again. [sigh]
2. Make a straight, short sleeve pattern in oak tag.
3. Buttonhole guide for collar band.
4. Long sleeve pattern with shirt sleeve placket and cuff.
5. Study/test block fusing of collar
