I thought I would also whip up a neck warmer, except I don’t have any rice! Will update once I finally buy some rice. This one was easy and I didn’t use a tutorial. I had a piece of fabric folded in half that would be long enough and wide enough. So I simply turned it right side together, stitched along the bottom and up one side. Turned it right side out, and once I’ve partially filled with rice, will stitch the opening and probably top stitch.
