You can join the craft club even if you don't have kids or grandkids. Kathy is correct in thinking that the kids were included to keep them busy, however, they were also included because the crafts we will be doing will be fairly easy. For example, we might make those shrinkable styrofoam hats or a sock snowman. These are things that are easy enough for kids (sometimes with help) but adults will have fun doing as well.
As for what crafts, they will all come from the FC website, I will either choose one myself and post it OR I will present a list of three choices. There would be a poll and everyone can vote on what craft we should make, there would be a deadline for answers.
Hope that clears things up!
