I am definitely going to start making this the moment I find out that I'm pregnant. I love that you can make this quilt in little bits at a time. All the bright colors could be for a baby of either sex.
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.
