LOL, Trust me, there are millions of upholstery fabrics out there. You just need to go to a decorating fabric store to get upholstery fabric:) The only way you are going to find upholstery grade fabric on line is if you know exactly the brand and collection you want. Then you contact a place like www.eadeswallpaper.com (who would have guessed they sold fabric!) and you get a qoute and order if you like the price. There are hundreds of mills that sell hundreds of designs, so you need the product information. For instance, I just ordered Kravets (brand), Allure Velvet (collection) 14743 (style number) 135 (color code). Upholstery grade fabric is determined by many elements: the ply and twist of the thread, the weight of the thread, the weave of the fabric, the dye, the finish and any decorative embellishments. You can take a finished upholstery grade fabric, embroider all over it and make in totally unsuitable for upholstery. You could find a med. weight fabric that feels like upholstery grade, but the weave may be inappropriate. Likewise, some silk dupioni, which is a light weight fabric, can be used on upholsterybut you have to apply a knit backing to it first. Other heavy silks cannot be used on upholstery due to its weave and finish. Truly, the mill has to determine its use. All fabric manufacturers will mark their fabric for end use. Flip to the inside back of the fabric book for the list of end uses. If the fabric is rolled and hung on a display rack, look on the hanging tag. If it is not marked and you are in a reputable decorating fabric store, ask the salesperson if it can be used for uphostery. Generally speaking--and this is assuming you are in a decorating fabric store--if you see a fabric the weight of shirting or a bed sheet, it is not upholstery grade. Most likely for drapes and throw pillows. Look for something the weight of a heavy damask tablecloth. Then ask to confirm it is suitable for upholstery. The linen will probably feel rougher than you envisioned, but it will soften in time and washings. Have you considered purchasing a slipcover? It maybe a lot less trouble. Many places will custom make it to ensure a good fit.

I'm going to agree with annie. You're asking for a mess if you try to stuff those two into a cover. The cording will both show and be felt when someone sits on it, and given time, will wear on the velvet differently and leave a pattern of the cording. That stuff needs to come off. Personally I'd then lay the two foam covers together and draw around them as a pattern on paper, then cut the same shape from a high quality upholstry foam. Then wrap the foam in batting as noted above, and muslin slip. Then make your one cover removable if you wish. If you can't get the new foam, rewrap the existing foam instead. But I do think after time it will separate somewhat and again, ruin the look you're after by leaving a gap. You're working with a very very hard fabric, and trying high level techniques (cording with a quilted velvet). I am very confident with this stype of stuf, and the thought makes me want to curse in advance for you. I do recommend that you first make a muslin pattern before you try cutting the velvet. Velvet walks away from you when you sew it face to face so be sure you pin the heck out if it (use french silk pins). And as to the cording, don't even try if you don't have or won't pick up a cording foot for your machine (which you'll fall in love with). If I were making this, I'd first make the muslin pattern (hopefully you've figured that out in your discoveries) and then try to make it up using cheap cording with a cording foot and be sure you have your technique down. Then, if that comes out well, go ahead with the velvet, but remember, more pins verses less, and I like to use two with particularly slippery velvets. The pattern will be lost if you try to remove the velvet backing (or the quilted batting) and it would be a huge amount of work for something that won't even show. I'd find a nice contrasting fabric or a velvet that matches without batting. But again, personally...I'd not do the velvet cording because it's a pain in the kiester! I'd do it in silk dupioni in the same color which flows well with the velvet and is easy to sew.

The labor to make the slipcovers is costly and well deserved from my point of view. I had slipcovers made for my two couches, the fabric was 850.00 and the labor was 1200.00. To me it was worth it since the couches are flexsteel and very comfortable and I love the style. Yes I could have bought new sofas but not with the linen I wanted and not flexsteel. In my lakehouse I have a stretch chenille which works well enough but you have to keep fixing the cover to smooth it out. I think I paid 100.00 for it.

Need to see the room. Can you post pics?
