Hey LJ, nice job! Where'd you get all the materials from?

Crap, I missed your post. I just used a staple gun, cheap and fast. No messy glue...Glue can be messy and I worried about the long term adhesiveness.
I used a natural Burlap - kinda beige in color. Yours is a nice greyish/white. I might order some of that stuff to add a second neutral color. The only hard part I found was pulling the Burlap tight enough around the frame so the panels looked professional and square.

I've been so busy lately I still haven't finished all my panels. Haven't done any DIY'ing since October.

I have a few pics somewhere at home of my panels...I'll see if I can't find'em and post em.
