I found a solid black backing fabric that has a silky feeling. Loved how it worked in my quilts. Still have a bit of it left and will be using it for my Bricks and Stones 4-patch blocks. Can't remember where I got it though but it does ravel somewhat. Only drawback I found with it. It didn't bleed, seems not to wrinkle too much and I know its 100 cotton. Sorry I can't remember where I got it though. I think it came from my local fabric store but I purchased it early last year so I doubt if she has any more.
