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.
Great idea: "For this blanket, Jane used double moss stitch and knit five "scarves" that were then sewn into one big blanket." Find a scarf pattern (or two) and then make scarves in to a blanket. More interesting than knitting a whole blanket!
