Find something really unique. I have found shows before payday the 15 & 30 of the month have less sales then those right after pay day. Also accept credit cards. Point out what makes your things special - Pre washed fabrics important to some buyers, larger size pot holders rather then 6", imported from Africa or Australia fabrics. American made fabrics. All machine sewn or all sewn by hand. As someone else said Make what you enjoy doing. Color sells. Keep similiar things together. Good luck. Keep us posted.
