I was looking at kits to make candles, soaps etc. Just not sure if anyone buys this stuff. Also looked at web sites like web whole salers to see if they have any stuff I could buy wholesale and sell at the flea market?For a few bucks for my kids?What is popular now?
What sells?

How old are your kids? Ask them what their friends are wearing and buying, then start from there.

You can also make a community website for your kids and their friends to hang out then sell ads..

I am going to do custom T-shirts with my daughter this year and sell them on www.Etsy.com

I guess you can make bracelet and hair clips.
