Hi, I am from the Boro. The Fiddlers Jamboree!! That is a great bluegrass festival. Let me know what booth you will be at I will stop by and say hi. You will have a blast there. You need to come to Uncle Dave Macon Days in the Boro in July. I demonstrate there in April and October. If you are looking for more ideas you should set up there for there spring opening in April. Contact Cannonsburg Village through the Parks and Recreation Dept. I think it is pretty reasonable to set up very minimal fee. It might help you figure out what you want to sell.
I demonstrate basketry, quilting, bedrugs, and tatting there also at Ellington Agricultural Center on Edmonson Pike in Nashville, they are always looking for craftsmen for their events. If you are interested contact the museum and ask for Ann Dale she will help you. Good luck to you.
