I made this for my husband as part of a Crochetville CAL.   A woman was cleaning out her storage and found an old drum (like a kettle drum).   It needed repair and when the top was removed she found an afghan inside.  She figured out the stitch and started a crochet-along called the Drum Afghan CAL.   I like how the colors blend because each of the four panels is done in a continuous piece, but still looks like individual squares.  I had fun with this one!
