You made 21 quilts!!!!! I'm excited that I got 1 completed for our local group's charity cause. I've seen your postings of some & you have nothing to worry about. If you have reasonable prices you should be seeing them fly off the table.
Do you have signage stating where $$ ends up -
i.e HELP A HEART (all proceeds help children with heart disease). Big & bold kid print should attract potential customers & might tug at some hearts. Got a kid around to write it for you?
If the QP show up, remind them that it's 'National Quilt Police Appreciation Day' & their boss told you to relay the message that they have the day off. LOL
Good luck & let us know how it all went.
