I would donate the minimum dollar amount received for the quilts.

I may just give them a "blessings on your efforts" - and perhaps an explanation of why I feel that way.
I did notice at a fund-raiser that I attended - males seemed to be "in charge" during the auction - and that "womanly - needle-craft" hand-crafted items did not get the same attention as something made of wood or metal.
