I'd try some of both. If you have time to make a block for display of each quilt kit pattern it would help market them. People love to be able to touch and feel. Not for each kit, just for each different group of kits and maybe have them hanging up with little clothespins. They could be numbered and have the kits numbered accordingly. I'd love to be able to purchase a 30s/40s kit with white background, the black and batiks that you've been doing are superb, maybe some in country colors, etc. You could do some scrappy, some not. Since you're going to have a large variety of people, you'll want a large variety of kits. Try Marshall's Dry Goods online store, they're fairly inexpensive and it's good fabric. Their blender bundles are fantastic.
