Here are my awesomely adorable wristcuffs that i threw together for the grand finale of the Harry potter book parties!
They're made from crappy redheart, but my friends and I loved them anyway, and wore ours the whole time we were reading the books haha.
There was no real pattern, i just sort of casted on, and went for it.

Pattern for spiral:
http://farm2.static.flickr.com/1079/992205821_da10e7a78b_o.pngyarn: worsted
Needle size7 dpns
cast on as many stitches as is necessary to fit around wrist, there isn't much stretch, so it should be just big enough to fit over your wrist. I cast on 30, make sure it is divisible by 6 and it was a little tight.
Knit one row MC
begin color pattern in stockinette, carrying the other yarn behind m=main color, c=contrasting color
continue on until long enough for your tastes, mine are 3 inches long, cast off using main color.
Thanks for the compliments, if you have any questions, let me know!
