I also finished all the green and the aqua blocks for my Zigzag rainbow quilt and am now working on blues, from light all the way to dark, with some starry skies thrown in.
Speaking of blue, I have also been finding more resources for info on antique quilts, on blogs like Barbara Brackman's Civil War Quilts, and also on Pinterest. I have pretty definitly dated my scrappy medallion quilt as 1840-1865. What a thrill. Here is a closeup of some of the borders containing Prussian blue, typical of the period.
I especially like the Prussian blue flower on white near the top center. The quilt has been well used and laundered, but that is part of its charm for me. I like it to give old quilts a good home.
