Knitting

A suggestion I learned from my mother, the constant knitter: when you buy yarn, rewind it into balls before using it. To do that, wind it around your fingers to start, and when there's enough to hold, wind *over at least three fingers* so that the yarn doesn't get stretched out and stay stretched -- you will want it to be able to stretch in the finished product, not the ball. Work from the outside of the ball (not the inside), and if it tries to get away from you, put it in a bowl on the floor (or similar thing).

It might help.
