I'm a huge fan of FB and would join the local groups that sell stuff similar to what you are making, and then post on it regularly.
I check out Craigslist several times a week and have found some good deals on there that make it worthwhile. A friend sells on there for a living and she said that the competition will flag you and get your ad removed, so you have to keep posting over and over again. She buys storage units at auction like they do on the TV show and sells most of it on Craigslist.
I have several friends that sell at the different Trades Day flea market type things we have here. Canton is the biggest, but they drive farther to Mesquite, which is closer to Dallas and sell there. They have learned that they can make more money there. Most of what they sell are plants, but he does make a few craft type projects. A good day for them is $500 in profit.
