Here's another needle question.This has been bugging me for a while...if you use a lighter fabric you use a 75/11 needle.If you want to stitch a design that requires a cutaway backing (not the mesh type) on that fabric doesn't that change the density of the fabric? Do you go to the next size up? My cutaway seems fairly heavy(like pellon interfacing),unless of course it is the mesh type.....What does everyone do? I'm in a muddle here.
