I've been finding lots of yarn at yard sales- usually only a skein of each color. So, I decided to try making an "afghan of many colors".
Start by chain stitching about 38 stitches. Turn and single crochet back across starting in the second chain from the needle. When you get to the end, add three chains and single crochet back across the bottom of your piece. You should end up with a skinny rectangle.
Then take a new color and attach it anywhere on the rectangle- chain three and then double crochet in the next stitch- continue double crochet stitching all the way around the rectangle-
(when you come to the corners put three stitches into one of the single crochet stitches, mark center stitch, and then continue around).
When you get back to the beginning of that row attach sides together with a slip stitch and tie off.
Pick a new spot on the rectangle and slip stitch on a new color. Chain three and then double crochet in the next stitch and all the way around. (don't forget the three stitches in the corners). Repeat.
If you feel like one you'd like longer sides add a few stitches to those edges. Just make sure that you add the same number on the parallel side.
Every now and then single crochet around instead of double- just to mix things up a bit.
I'm sorry. I know these directions aren't that clear- it's really an easy project!! You just wing it. It's great to work on while the kids are around because you don't have to remember a stitch progression or where you left off.
