We will be offering a video on our website, UniversityOfFashion.com, soon but in the meanwhile, here's one quick fix: Measure your bodice's armscyse and compare it to your total sleeve measurement. You should have a 1 -1 /4" difference on the sleeve for ease. To adjust, open the sleeve center up and either add or subtract, then reblend the sleeve cap. If you need to subtract the sleeve cap, be careful not create a smaller or large bicep. To avoid that, slash and spread the sleeve center pivoting it open from the sleeve hem. Why not join U of F to learn all about patterning? We are much more affordable than craftsy and other how-to sites. All of our lessons are taught by fashion college professors and industry pros!
