Great advise Lori S. I've been selling at craft shows for about 10 years. I have a mix of quilted items in the $20-$50 range then many items $12 or less (grapevine angel & stars & whatever else sounded fun to make & looked catchy). The lower price items almost always sell very well; sometimes sell out and they draw people into my booth, when, occasionally, someone buys a higher priced item.
I often have customers tell me my items are very reasonably priced, but in this economy, they're just not spending that kind of money. Around the holidays, I sell lots of grapevines pieces as the smallest ones are $10 & under - the price limit for many office or other gift exchanges.
