Sewing is weird in that, at least with hand sewing, there are as many subtle components as there are obvious components. For example, a lot of stitches end up hidden, so unless someone tears apart a piece, how are they gonna know? Each time I make something, I learn something, from how a certain fabric works to a better way to hold my piece to learning how to make more consistent stitch lengths. Messing up something, for me, is the quickest way to learn something, and I've made a ton of learnable mistakes that have influenced how I want to piece things, how I treat my fabric and threads, how I keep my needles from breaking, etc. Five embroidery projects from now, look at the backs of those pieces and compare them to the pieces you just made. You'll have made mad improvements, but because the backs are hidden, no one will know, except you. The gap is big, but it's easily traversable, the gains are there, but they are often hidden if not outright inmaterial.I feel with these kind of crafts, it's usually quite easy to be "acceptable" but then the gap until "good" is pretty big.
