You'll also need a coffee cup, small basket, vase, or other container about 5 inches high with tapered sides.
Step 1: Start knitting or crocheting a simple rectangle
Do use loose stitches. If you have large knitting needles or a large crochet hook, by all means use that. I didn't have any, so I'm using the handles of my two largest paintbrushes. The ends of the brush handles aren't very pointy, but it doesn't really matter because the stitches are very loose.
In this picture, I'm pulling and stretching the work apart a bit so that you can see how loose I made the stitches.
