Sock yarn comes two ways. A skein will have either enough for one sock or enough for the pair. Since I like to do both socks simultaneously I usually go for the smaller single sock skein. I found some yarn that I really like but it came in the larger quantity for making the pair. It's kind of pricey so I'm wondering what the best way to divide the skein in to two would be rather then buy a second skein. I'm thinking use a scale but maybe someone has a quick and easy trick for this.
