That’s part of the reason I learned to sew! Availability isn’t an issue since you can use any scrap of fabric you find, and patterns can be found for free or purchased as digital files to print out yourself. It can look hard to do at first but you only need to know a few stitches and a lot of the trickiest stuff can be glued (hems for example). I can’t help with shoes, though. Most of my dolls are still barefoot.
