I'm working on the Trilobyte hat from Knitty.com's Summer '09 issue for my BIL who is a geologist. He has a lot of fossilized trilobytes at their house.
However, it does require cabling, and I walked out of the house without a cabling needle. My crochet hook is just too awkward and long to use and I'm incapable of just taking the stitch to be cabled off the hook without it laddering downwards. I was a tad frustrated at what should be a simple cabling project.
As I was eating lunch with chopsticks, I thought, "Hmmmm....." So, after lunch, I washed said chopsticks and used my scissors to score the wood so I could break it. Then using a handy-dandy pencil sharpener to give either end a point, I made myself a small cable needle.
It works just fine.
