In my guild I used to run the BOM program ... we charged .50 cents for a kit ... sometimes it had all the pieces and sometimes they needed to supply a piece ... depending on budget. We had a lot of participation. I had other obligations and gave it up ... the new person supplies the pattern and sometimes a piece of fabric ... we supply the rest. The participation has went way down. I think most of us are busy and if they can just sit down an sew the block they will participate and if they have to do more of the leg work they won't ... everyone has busy lives.
