Usually these are made from real bamboo branches/stalks but I thought, why not use chopsticks? Originally, I wanted to use disposible ones that you can just steal from restaurants, but I suppose I'm a little adverse to stealing? I just don't go to those restaurants very often. I was going to use the plastic wrapping on those to weave them together but I just decided on real chopsticks. You can by these things at ikea and a lot of places, they use these kinda things to roll sushi also.
Cost: Low: Free if you're family is asian, or if having 30 sets of chopsticks lying around is your kind of thing
Time: Low: 10-15 minutes
High: 25 minutes
Go to your local asian store or Chinatown, shouldn't be too expensive. Mine cost me a less than dollar fifty(9rmb). But I'm living in China now, so pretty its cheap. 10 sets of chopsticks for 3rmb.
