Have you looked at Lee Industries? They make a slip-covered product called Coveralls. Their frames are 8-way hand-tied. An independent retailer in my city sells their line. I don't personally own their product, but have seen it and it looks nice. You can order swatches from their website. Here is a link that might be useful: Lee Industries

I have Peyton in "Oatmeal" color.... four of the 108"h x 100w panels.... They do have quite a few wrinkles out of the package. I steamed them for a while to get the wrinkles out, but there are some still there (I don't mind, and I could probably steam them more to fix it :)) I think they are good quality... certainly better than anything I bought at BB&B or big box stores. The lining is nice and filters light quite well.... ...bottom line, I haven't regretted this purchase.

Re-reading the original post, I see that you did say that you were thinking of a lighter fabric. I think that part of what I respond to in your room is the strong lines of the frame against the gray wall. I would not like to see that obscured, and I think you have just the right amount of fabric now, with the bedding and the curtain panel that is visible on the side. I was thinking of black and white framed photos, too, but I'd like to see three - I like odd numbers. I wish I could photoshop!

If you see a backing on the rug (as opposed to seeing the weave and pattern on the underside) then it has adhesive. The back of the rug is coated with adhesive and the backing is glued to it. That is what you smell. The latex adhesive deteriorates over time (avoid sunlight, this makes it worse). I read one comment about using an iron for creases - if the rug has an adhesive this will melt the adhesive and cause staining and smells. The first 3 days are worst for new rigs with an adhesive, but VOCs can off-gas for years. Recently, PB has started using a manufacturer that uses "synthetic latex" adhesive to combat this deterioration, and latex allergies. They claim it doesn't break down but I don't have long-term experience to know how it performs. It theoretically should have low VOCs and minimize smell issues. I'm curious if anyone has experience with their rigs made of recycled water bottles. They are more affordable and are surprisingly soft.
