What about holiday themed doll quilts?
Sometimes people will pay more for a small item than for a larger item.
Valentines - Halloween -Easter - Christmas - Fourth of July -
Or door banners?
I'm thinking you might have better luck with smaller finished items than a larger item that isn't "done"
For a "fund-raiser" type of thing, I might part with $3 for a pot-holder, but not $20 for an unfinished quilt top.
