Grunge has been very popular..It has a great matching capability with subtle color variances.
I have 7 flimsies paired with backings (2 are BH), 1 flimsy I need to get backing fabric, and the outer border to put on my little house quilt, "Nothing But Blue Skies" as well as finish quilting the last 2 borders on the "Crazy horses" quilt...guess I should confess this on the UFO thread!
Work tomorrow and Friday and have bookwork in between....thanks for sharing the BH mystery
