So i have a pretty deep scye and large chest, when drafting the sleeves the hand tool is too small to actually shape the top sleeve. If i pivot off point 4 then the tool falls well short of point 6. Is there another system i can use to actually draft it so i don't end up with a wonky shape that will give me problems when trying to sew in the sleeves?
Armhole circumference is 25 1/4, scye depth 11 1/4.
11 1/4" is quite deep.
Are you also very tall? Like 6ft 3"
Quickest solve is to just size it. Trace around the hand tool to some card and add a 1/2" all the way round.
