I participated in one craft fair so far. I sold cat toys with cat nip in them, cat mats with cat nip in them. They went pretty well. I did have left overs and gave them to my local animal shelter. I have thought of selling pin cushions of all kinds, table runners, place mats, beaded ornaments. I haven't got anything organized as of yet. I think smaller quilted items like wall hangings, table runners, would sell more easily at a craft fair. Also quilted tree ornaments. At fairs I have been too, crafters selling bed size quilts didn't seem to do too well, but it may be different in your area.
