you are my hero ! I bought a helmet pattern on Etsy, and having a larger than average head width, I didn't know by how much percentage to increase the pattern ... and there I come across your video. A huge thank you, for this 'magic' tool and for your work.
This is awesome! I'm currently trying to resize a body pattern but the pattern seller had a variety of measurements that are a bit not quite my size because the original cosplayer had a shorter arm span, bigger inseam, and bigger waist. Do you by chance have any tips on rescaling with multiple measuring variables?
