Well, I actually spent a few hours working on the layout today. It started with the trip to Menards to pick up the landscape fabric. It was even on sale, then I used up my rebate checks that had been sitting around for months. Final cost, $7.80, and that should finish the whole project. I think model railroaders are born with the "cheap gene".
I took two of the 4' wide rolls, and cut them in half on the table saw. That worked great, though there is a slight problem, and that is the cut edge melts a little, and it doesn't come off the roll freely. I can live with that.
Next I made this giant "paper towel dispenser" to hold the roll in an easy to hang orientation. I grabbed this piece of wood, which my last Menards delivery was shipped on, and cut half lap joints on the radial arm saw, then drilled a hole for a leftover chunk of conduit as a spindle.
It's not quite perfect, and I'm still getting the hang of it. It would be better if the material wasn't so stiff, but I guess you get what you pay for.
I'm going about 6" then fold back 1" to form the pleat. That seems to be about right.
I've actually built in an opening, because it's hidden in a pleat, it's virtually invisible.
Now that the setup is done, I can spend all afternoon on Saturday going up and down aisle one.
BTW, my knee is feeling better. I have a pad that I can kneel on as I get up and down.
