You could also do Block of the Month as homework assignments, taking the blocks from Quilters Cache. Give them the block pattern link each meeting and have them come back with the block done from their own stash next month. Lots of bloggers, including me, have pictoral BOMs on their blogs, so you could do a search for those as well. At the end of the year they have 12 blocks, and then you can look at adding borders and bindings using the links in the Links forum.
