Good luck on your sales!
Maybe do a search of what others here have done for craft sales.
I've had potholders, table mats, doll quilts, baby quilts, twin size quilts. Soft books, embroidered towels, table runners and some totes.
Others have had book marks, aprons and other small kitchen items.
Yes, make sure you have a good selection.
Just my opinion...make just so many of each thing. More of one than another if you think that item will be a hot seller.
Americana colors do sell well in certain areas.
Above all....don't overprice!
