I also have a craft room full of half started (half-finished?) projects and supplies for just about any type of project you could do. Minus painting. I've never imagined that I had any skill in that area. Sewing, crochet, decoupage, embroidery, paper mache, crystal wrapping, paper craft, scrapbooking, felt work, wreath making, um. yeah. I wrestle with that feeling still.
I bought a guitar because I thought that would stop the cycle of supply need, I can just play the guitar. Sadly, learning the guitar is hard and I am still in the very beginning stages. But I haven't been to the craft store in months!
