Hello yukkuri_kame What if there is a half an inch thick wooden Length in between Iron Angle frame & 6 mil Poly layer all around the greenhouse? Wooden length will bolted with Angle Iron & then Poly Layer will be attached to wood itself. See pic below. Hello dowlinggram, RoofTop is strong enough to support the load of the frame. It dosen't matter. Roof Top is tiled with bricks with cement in between them over a stong concrete structure.I have no need to construct benches in greenhouse. Please refer to link below: One or two pics are showing RoofTop Structure. Awaiting comments. Cheers. Here is a link that might be useful: Here, Roof Structure Shown in one or two pics.

This is a most riveting subject, and a most interesting thread. I think there is a little bit of truth in many of the posts so far and I've changed my mind on this one at least five times. The actual print inside the frame gave me the impression of a photograph because of the fine white line like old photos get when they are damaged. That being said, one can take a photo of a drawing and parts of this picture are without a doubt hand rendered including the background and that could very well be a studio backdrop. My impression at this point is that this is likely a studio portrait and that it is in essence a composite with the facial features being the true rendering off a negative and the rest a lot of touch up and very poorly executed outright embellishment. If you'd like to see an example of a turn of the century hand painted studio backdrop, I can show you a large portrait of my great-grandfather and his brother sitting in a real chair, but with a very fake staircase behind them. LOL It was not an unusual practise, clear on up to the forties and fifties for some photographers to take portraits in black and white and hand tint and retouch them in the dark room. It wasn't because of the cameras not being able to, but the studios having the equipment to develop them. So seeing 'sketch marks' doesn't prove anything but the skill of the craftsman who took and developed the portrait because you're just as likely to see the editing on a real photograph as not. I have a portrait of my g'grandmother I'm inserting here because judging by her age it would have been taken about 1918-20. It has been hand tinted, and if you look at her blouse, it has obviously been hand retouched for detail and the bottom darkened out to extend the photo as much as possible to the paper to fill it. I think this is what happened to the boy's dress......it was probably enhanced by hand and the chair by imagination and lack of artistic ability. Even poor people scrounged up the money for portraits in the old days, God knows my ancestors weren't rich people and we have them to pass along. But they certainly were special enough not to be done on a whim. One portrait my g'parents had taken in the twenties was of my little aunt who was expected to die at birth, but lived until two years. So, they coughed up the money, even with ten kids, to have a portrait taken of her. I'm no expert and I'm not pretending to be but before I'd blow this one off as a fake, I'd have it checked out. Regardless of how it pans out, and even if it turns out to be a Cracker Barrel nostalgia shot..........it's a Jim Dandy and worth hanging on a wall just to see the mug on that kid.

If your pillow inserts are feather or down, they will squish more nicely into the shape of the sofa. I have 20" feather pillows and love them. They mold to the sofa and your body and are so comfortable. Stiff foam or synthetic pillows will be pretty big at 20", depending on your sofa arm size.
