I didn't e-mail stillwater til late this afternoon and I got a response in the past couple of hours (good time).

I told him basicly the same thing I told you guys, posted the pics, and your advise.
He said
"That is correct. Looks like a crease was set into the kilt when it was folded up and stored on our shelves. If a bunch of kilts were piled on top, it could set a nice fold into the fabric. Iron it out with a warm iron."

So, I am going to iron it out with a warm iron. To get a crease like this out (well, two creases) should I use just the setting that says acrylic and low, high, or no steam?
