Did you use any type of backing? I am going to use silk.
No. I bought some linen to use, but I hit the red oak jackpot and found a board at Lowes with no run-offs and it wasn't warped. Lucky me!
I'd like to see a picture of that pulley system too. It's a good idea, but I'm a rookie and I haven't seen how it can be done. I assume I just attach a pulley wheel to the bottom of the 2 x 4 and set up something to anchor the tree down so it doesn't move when I pull...
