Hello neighbor
I live near EDH, and you will have a wonderful time finding inspiration for the FE's. I just came back from the local farmer's market, and you can get some great ideas just by walking around there. Walking around Old Sac, Placerville, and even the Folsom historic area might stir up some ideas.
Just a thought...Think about how many you can make and pack in your luggage. We had a large FE group last year and it took 3 carry on suitcases to bring them from the West to East coast. And then we had to buy one more suitcase to bring all the goodies back with us!
Have fun, I think personalized magnets are great, photo frames, and a Diser even made jewelry with a "Dream" charm on it.
Good Luck!
