Is your guild into machine quilting with rulers? Someone coming with rulers and demonstrations for home machines may be nice. If they could also bring Machinger gloves or similar and the sticky tape that goes on the bottom to keep rulers from slipping, I would like that.
How about a hand appliqué block work shop night with someone putting the blocks together and quilting for donation quilt. We really enjoyed the program where we divided into tables and played for squares or strips of fabric that we brought and rolled dice to see who won them.
