I just tried something for displaying pins. So far it is working.
I got three embroidery hoops. One big one and two smaller ones. I put black Aida (sp) cloth in each one, I put glue into the frame to hold it better. The pins poke right through. You can move them really easily if you want to add or rearrange.
Then I hang the hoops on the wall. The big one goes on bottom, then the two little ones go above on either side. Yup, you guessed it. It's a Mickey head!
I have never tried actually framing my pins. It seems too hard for me. But, this was really easy.
