First time selling at flea market! Help, please?

Rather than branching out too much, I would have a focus. Cat and dog stuff may do well. Maybe you could have breed specific items. I know a lot of people have these little designer breeds like, morkies, and yorkie poos and stuff (I image those kinds of tiny dogs are the kind people buy clothes for) and I don't see many items with the little designer breed names on items. Like "I love my yorkie-poo" kind of stuff. If you are just learning, don't make up too much of any one thing until you have a good idea what is selling. Also, could the body wash and shampoo and stuff be marketed for dogs? Maybe find some natural recipies with herbs that are good for dog's skin or something? Then once you get going, branch out to E-bay and other internet sites to sell. Soon you will be identiable as "the dog lady" or whatever and people will come and look for you for dog items. Make up a logo and use that style of lettering/colors everywhere (tags on merchandise, banner over your table, etc, business cards if you choose to use them, maybe even wear a t-shirt in that color with your business name on the back). Like, if you chose pink & black- do up your table with those colors, have a big pink banner with black lettering,wear a pink-T-shirt, pink & black tags (maybe cut in the shape of dogs) on all your merchandise, black on pink labels on your botttles of dog shampoos and lotions. Not that those colors are necessary, just get recognizable style and use it everywhere. Good luck!
