just a quickie as things are not good here. When you make your pattern either trace it out or print it out again so you have two copies. Number the pieces as in the pattern. Now cut the shapes out in the paper. Now all you have to do is place these pieces onto your fabric. Cut at lease 1/2" bigger than the paper. You should then have the perfectly sized piece.
Only know this because I was a dressmaker. :thumbup:
