I saw kits for pre-cut log cabin kits at a show and the booth was packed w/ customers.
Individual FQ's always seem to sell - whatever they might be - novelty, calico, blenders, etc...
So many people have a hard time choosing color combinations - maybe offer a bundle of 3 or 4 fabrics that are 1 yd each that coordinate.
I would consider selling color wheels - or display a few near the fabric for customers to interact with. I carry a small one with me when I go to shows.
Would Holiday fabric choices sell well at that time of year?
Are people expecting to see Amish style products in that area?
