Every time we go camping, I wish we had a hacky sack. Since we can't buy one around here, and everytime I'm in the city, I forget to get one, I decided to make my own. At first, the instructions called for embroidery floss and a really small crochet hook. It was too small for me to see what I was doing, so I practiced on yarn first (and got a humongous one), then tried it with floss (and got a tiny one), so now I'm working on a third one. Hopefully this one will come out right. Its amazing the things you can make with a little effort.
