What did you decide about the fund raiser?
I completely ignored the first question about size and went straight into the fund raiser portion...
I make quilts for 2 groups-QFK's are about 45x50 for younger kids and 50x60 for older kids/teenagers.
and QOV's- 55x60
When I make baby quilts for friends I try to make them 40x45-50 so I don't have to piece the backs.
Fund raiser projects that migh be good: pot holders, tote bags, coaster sets, small things that can sell for less then $10 are good...
Unfortunately people go to these type of sales looking for bargains and not so much for qualtiy.
