This had been on my "to do list" all summer and 2 days ago I finally got around to doing it. Fabric, lining, wood, 2 screws and o rings from stash, bought nylon string and curtain eyes & hooks.
Instructions on how to make it are here

I stapled the blind to the wood, but the velcro is a fab idea if you need to wash it regularly. I only used 3 rods and next time I'm going to sew the rod pockets to the lining before I attach the 2 bits of fabric together.
Anyway the arrow in the pic is where it is secured to a cup hook. And it's only partially up.
