I have done 1 show for 8 years & every year can be different. This show runs with the Lions Club Chili fundraiser so both benefit. Weather can also play into the success of a craft show. I mainly have quilts, usually sofa or lap size. Another woman does baby size, wall hangings,10 min. table runners & the crayon aprons so I try to duplicate what she does. The organizers also need to advertise. This year we had great advertising & had a lot of traffic. Also think the chili sales were up. I have 2 more shows in Nov., both of those are 1st time shows so we will see what happens. The 1st Sat. in Dec. is the biggest show date. I think there are 6-7. Too many to get to in 1 day & I only covered booth charge when I did a show so decided that day was not worth the trouble.
Check out a few shows this year & see what seems to be a good fit & try it. You need enough items so you look like a serious seller but you don't need to stock a store.
