I just did that for the first time this Fall. I stuck with quilted items rather than craftsy items. I made about 40 table runners in a variety of sizes, 6 sets of placemats, several lanyards, four baby quilts (really simple ones) and coasters.
It was odd what folks looked at. I did sell 22 runners. People wanted either really long runners or small runners/toppers. The ones that were more complicated I asked more money for such as Lemoyne stars and they did not sell and neither did the coasters. A few folks bought the lanyards and I sold two sets of placemats as well as 2 out of 4 Baby quilts.
My guess is that it will change form year to year and location to location but will do it again next year.
