Knitted projects rely on the three basic skills of casting on, knitting, and binding off. Friendship bracelets allow you to practice all three, and they are fun and quick to make. Knit them in solid colors or stripes, narrow or wide. Ask other knitters for odds and ends of medium-weight yarn, or get together with friends to share skeins. You can adjust the size of each bracelet by changing the location of the snaps.
