Knitting Threads I have more questions for you! I have been playing around with writing my own patterns for a bit now and would eventually like to sell them. But what I'm stuck on is figuring out different sizes. Do you make one prototype in your size then math it out for the rest and just have your testers work on the different sizes and hope the math is right? Where can I learn how to do that kind of math to make different sizes? Resources for learning to write patterns? Help! 😫
