Just from my experience, and I do a craft show every weekend all year long-I know finished things sell better for me. I tried some kits and other things and people just didn't want them. Finally sold them on ebay.
I have a variety of items from coasters, potholders, placemats, table runners, wallhangings. In fact, I have over 4 tables full of items.
Also be sure to check that you can sell items that aren't handcrafted, like your books and fabric. Most of the shows I do anymore are getting real picky about everything being handmade that you sell.
If you have any other questions, I've been doing this for a number of years, please feel free to contact me.
Hope you do well. Just a warning-its alot of work!!!!!
