my friend does craft shows and the mans apron thing sold several (I didn't get the appeal myself) but she only got 12.00 for it so it depends on how much time will you invest vs cost vs return.. why would a pot holder have to be poorly made? do a flip it inside out with INSULATED batting only in it and you can have a nice item still, maybe not bound but the time invested is not intensive and everyone who cooks uses a pot holder. table mats, runners (check out my swap for ideas) ORNAMENTS people buy ornaments. In my six craft shows I have done ornaments were the biggest seller followed by wine bags. make them cheaper than you would buy a paper one is the trick. satin ribbon as the ties at the neck. one does not have to be a sewing wiz to make those. I sold over 100 at one show. . and yes under 10.00 is the trick to big sales, under 5.00 is an easy sale. quanity.. and antiques are anything over 50 years is my understanding so not necessarily Victorian or early Americana I think. Could be atomic era or groovy 70's lol so mix it up.. if you sell fiesta ware use fabrics that match up. button holders? jars with cool lids fabric covered.. check out the ornament swap this year. there are tons of pictures posted from 2010 swap and 2011 maybe you can borrow an idea?
