I buy from reproduction fabrics.com. Margo, the owner, is an expert on reproduction fabrics. If she says it's civil war reproduction then it's authentic. The movie industry consults her a lot when it comes to period films. There was a great CW film a couple of years ago (can't remember the name but as good as it was it didn't be come a block buster) for which she supplied the quilts. And if you have questions, you can get answers. I try to stop there whenever we go to Montana :D
