Formula for changing the size of Armscye
I was reading my pattern drafting book before going to sleep the other night and discovered instructions for lowering the arm hole opening and making the corresponding sleeve fit the new hole. It said that if I wanted to lower the armhole 1 inch then I needed to lower the outside corners of the sleeve 1/2 inch on each side . My question is does this hold in reverse. If I want to raise an armhole to improve freedom of movement and sillouette etc. do I raise it by half the amount on each corner or is that not right??Do I need to change the cap of the sleeve as well??
