I did this in first grade and have always wanted to try it again. I thought maybe I had been remembering wrong all these years. We have a project for this week. straw weaving diy (great project for kids)
Genius slipper design where you knit a short "scarf", fold and sew onto your bottom. Garter stitch extra chunky yarn about wide, and however many rows you need, then sew into the 2 layers of the felt bottom.
