It's kind of smooth, but it's not. It's kind of wavy, but it's not. It's kind of holey, but only when you hold it a certain way.
It's definitely very interesting. It's packing material that came in a recent order of art supplies, and I've had it on my desk for weeks, wanting to do something with it.
Unfortunately, embedding it in molding paste is not the right thing to do. In order to make it stick, I had to keep pressing harder and harder into the paste, until it lost its different facets and just looks like a flat piece of paper. Not exactly the look I was going for.
I'm sure I'll keep trying different things with it. Maybe I'll try sewing it next time.
