A CAL is basically a group of people all working on a large project at the same time and pace. Some are targeted to more advanced crochets and involve a variety of difficult stitches. Others are designed so that everyone can participate, no matter their skill level. Often the pattern chosen will be an afghan, and while everyone does the same pattern, each individual chooses their own colors.
Over at the Pippin Crochet Club we love CALs.
