A couple of things you might want to look at, what kind of show venue were you involved in....
Some shows do not really cater to the real craftsman... some allow just about anything to be sold and this means that the bargain hunters are out in force and those of us who make good handcrafted goods are at a disadvantage...
Been there, done that, have the Tshirt to prove it and won't do it again... LOL
Look for shows that are truly craft shows.. the best are usually juried and limit the amount of crafters that do the same kind of work...
I am the only pen maker in the 3 shows I do every year... I get a good following and have customers contacting me after the shows are over.
