I bought these blinds to sew my own fabric to the front not knowing for sure if it's possible. It is! It's very easy to detach the front part without messing with the mechanism. The back is white and the mechanism is a sturdy silver drum. It works perfectly. There's filmy white netting material that rolls up into the drum that's left behind after the detaching. Once you sew your fabric to the front simply sew it back onto the netting in the same places. Both the front and back Velcro to the header I assume for easier installation. I'm so glad I found these instead of the messy cord ones! I wish I could upload a picture of the back. Don't use too heavy of a fabric. It can take the lighter to medium weight upholstery and decor fabrics though. They measured true to size for me also.
