I have been doing craft/art shows for a long time. Pick your show carefully. Low table fees don't necessarily mean you make more profit... it may mean they have trouble getting crafters because the attendance is low and no one wants to come back and sell again. Pick a well attended show one that has been around for many years that has a good following of customers. Juried shows ( one you have to submit work samples) are nothing to be afraid of... it means the organizer can be picky as to who gets a table because all the crafters heard its a good show to sell.
Give it a try just do a bit of research ahead .. FYI the big( most successful) fall shows are putting out their applications now.
Maybe find a buddy to split a table .
