Mold Update

I'm trying to figure out what to do next with these mold pieces. They're subtly beautiful on their own, and I don't want to do anything that's going to overpower or ruin them. On the other hand, they feel incomplete as they are. I need to do something more, but what?

One of my teachers, Jim Murray, said I should let the issues determine my choices. What techniques and what additional work will complement what I want to say? The thing is, I'm not sure what it is that I'm saying. It has something to do with the ugly being beautiful, and it's also about old things and decay. But do these pieces say that? This is hard for me, and I'm feeling paralyzed right now.

I also have to think about presentation. Will they be on stretched canvas? Framed under glass? Mounted on board? Not mounted and hung like fiber art? And what will hold the pieces together? Glue? Stitching? Safety pins? Rusty nails?
