Materials

- Cards. You can buy a set of premade cards, or use a deck of thick playing cards to make your own.

- Warp and weft string. I used #8 perle cotton; 8/4 cotton warp is also a good choice. You'll need quite a bit even for a short band, since each card requires four warp threads, and you need to leave plenty of room at the end of the warp to turn your cards.

- Something to beat with. You can use the edge of a shuttle, a seam creaser, or (as I did) an ordinary comb.

- Things to attach the warp to. I used two large carabiners to tie the thread to, plus velcro straps to attach the carabiners to a) my bedframe and b) myself.

- Semi-optional: thick cord or scrap fabric, and a flat, rigid object. These let you start your band off evenly and neatly.

- Optional: a shuttle for your weft. You can also just make a butterfly of thread, or if it's small enough use it as it came.
