I would say putting notices at the Jewel/Dominics etc and maybe an add in the local papers. You will probably need to make sure you specifies “home made crafts” or you will get a bunch of companies like Avon & Pampered Chef.
Also, my mom would be interested in signing up herself for the show. She makes placemats, table runners, bedding, curtains etc...
Her email is ____@____.com
Good Luck!
