Metal Turkey lacers can be made into lovely stilettos with added glass beads. I was gifted a fancy one with dichroic glass beads from JoAnn's. Tea Wallets (tea bag holders and sugar and powdered lemon packets) and credit/store card wallets are made with less than 10" pieces of fabric. I make them with lightweight fusible to add body and fusible Velcro instead of buttons. There are many ideas on Pinterest with links to free patterns. Small snap top containers in the office supply section of the dollar store are great for bobbin holders. Threaders are always handy. How about a raffle ticket in each participant's package for a set of FQ's or other goodies? I've gone to retreats where folks can bring a FQ or unwanted quilty items like a book or UFO and they are raffled off.
