How about asking members of your guild what they would like to attend? Another suggestion would be teaching how to corral your stash. Bring bits and pieces of leftover fabric and show how to cut it into strips, squares, etc., and how to label boxes to keep the stash under control. Quick quilts or projects to get the new year off to a good start. A workshop I actually did was on quilting notions. Hope this gets the creative juice flowing. Good luck.
