I have cut out the Double Dutch block and hope to make some progress assembling it tomorrow. Obviously, pictures will happen tomorrow.
One would think, or expect, that a block named Double Dutch would have some historical background. I haven't been able to find any information about it, so I think that maybe, just maybe, this is another block original to this book, Marsha McCloskey's Block Party: A Quilter's Extravaganza of 120 Rotary-Cut Block Patterns (Rodale Quilt Book).
So, look for tomorrow's post.
And, quilt on!
