Formula for changing the size of Armscye

mem | Posted in General Discussion on

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??

    I think the answer to your first question is yes. If you visulize the armhole as a circlular hole and the sewn sleeve an another circular hole, they have to match. If you make the armhole smaller (by cutting it higher in the underarm layer,) you should do the same to the sleeve. I would not change the upper portion.
