This may not work for this year, but if you decide to go back - my mom does hand embroidery on flour sack towels and has them at her church booth every year and she almost always sells out and takes some special orders.
It is normally a hit n miss - you never know what people will go for. I am thinking that table runners may be a good idea. Also if you are doing baby items I bought my mom a pattern (can't remember the name of it) but it is for a cover that attaches to a baby carrier (hand held one) Can you tell I don't have any kids! anyways it acts as a barrier against the elements (sun, wind, etc.) One of her neighbors told her that all of the moms think it is the greatest.
