I want to start making my own patterns because I can never find exactly what I want. The thing is, I have never stretched anything! I don’t even know where to begin. I see it in my head but have no idea how to get it in a pattern. I am horrible at drawing but my imagination is endless. I have often created something (like a skirt) just by measuring my waist (and length wanted -for example) and using that measurement to cut the fabric. Where do I learn to do sketches?
