Someday I’ll write down an actual pattern and post it. Basically you just make a wide tube with Tunisian in-the-round technique, using a double sided hook and two different yarns. Switch to a new type of stitch every 5 rows or so, try to alternate between curling and non-curling types. Once your bag is approximately half the intended height, or you run out of stitches you know, then exchange your forward pass yarn with your backwards pass yarn and repeat the entire first half. This gives you all the same patterns again, but switches the foreground/background colors. Once the tube is done, use a frilly cast off. Then, make a thin flat band, very long. Long enough to wrap all the way around the tube height-wise, with enough extra to make a good strap, and then enough extra again to match shoulder-width. Sew the middle section of the band to one open end of the tube, such that it is closed off, and then up either side. Take both free ends of the band, overlap them shoulder-width, then sew the overlap area together. Then it’s done!!
