You’ll probably have to compromise if you are looking for ready-made rugs. Six-by-six I’d guess is an odd size. It’s hard to find rugs that are square. Six-by-seven you might have more luck with. If you went up to six-by-eight, I think you’ll have more luck.
If you go to a carpet store, you can get any size you want. Sometimes, pretty cheap off the remnant rolls, too. Then have the edges of the carpet bound (stiching is best, but sometimes they’ll sorta “hem” it, or take a piece of fabric and fold it over the edge and sew it down- cheaper but less good.) and voilá: a rug.
Wool is just bitchin’ as a rug, if you can afford it and don’t have allergies (or kids, or pets). Don’t get it wet though, you’ll have a felt rug in no time. (But REALLY good ones stand up to moisture.)
Scotch-guard™ can be your best friend. Other versions of it can be good too. Just something to keep the dirt from penetrating the fibers. (Or if it’s an English rug: fibres)
Olefon. I think that’s the name. It’s a pretty good fiber for rugs. It’s pretty standard. All one fiber is better than a mix of fibers in the same rug. I forget why, but that’s what everyone said when we were looking for carpet. (The rug in my living room is 100% Undetermined Fiber- see? all one fiber type. And boy does it look good. You can get some swank stuff at Sam’s Club.)
If you’re looking for Oriental rugs… no idea. A little too spendy for me. And the cheap ones are ugly. If you do want an Oriental rug, talk to the owner of the store. Get as much info out of them as you can. Then talk to the owner of another Oriental rug store. Repeat untill you can’t take it anymore, then buy the first one you see that ain’t too ugly.
Rug pads are a good idea. A rug on a hard floor needs one so it won’t slide. Even with furniture on it a rug can slide. The pad also keep the rug nice longer. The tufts of yarn don’t get all mashed down so fast. A rug on carpet needs a pad too. You wouldn’t think so, but they can slip around like crazy. A waterproof pad can be a good investment too. It helps to protect the floor.
And get a nice burgandy berber rug. With hunter green edging. The color will bring out your eyes, and compliment all those stunning antiques you have littered about the place. Nothing too busy. You don’t want to over do.
