Rex has a good idea, look at the odd shops, garage sales, Goodwill, ect. I am sure, in Az, you can find a Kokepelli brooch, that will make a very nice kilt pin. Pawn shops might be another option, but the prices might be a bit higher, since hopefully, the items will be made of silver( look for the numbers 925 stamped on the back). What will make this pin more special, is the journey taken, to find it. I lived in the northeast part of the state and I had the pleasure of traveling many parts of the state.. Very beautiful.. Could be an excuse for a decent road trip... LOL you never know what you may find, and to use it for a kilt pin..Good luck and have fun! Oh yeah.. You have to wear the traditional search clothes too... Plaid shorts, sandals with white socks, and a Hawaiin shirt..topped off with a straw hat...LOL
