Well, not really. Just the math part, and making sure things will fit, or stretch enough, or how a fabric will hang, or worrying about if stitches will come undone or your needle can’t sew as many layers as you have to sew together, and trying to attach 5 different shapes together to make a 3 dimensional thing, and to make sure no raw edge is showing on ANYTHING cause then the whole thing will just unravel, or you can singe it and have a brown and burnt smelling edge. I need a mannequin my shape. And ricrac and elastic thread, and zippers and lace and to learn how to shir fabric. Or sew elastic bands into things. <: sewing hard>
