Yes, that is the idea---but the only difference is that I don't initially cut strips. For instance, I am making 4" blocks, so I cut the blocks 4 1/2"--a block of each color--you sew them somehow--then you cut them into 2 1/4" strips--sew, then cut again, place them together, first interlocking the seam lines, and you get a finish like on the scan, except you really can't see the interlocking seams. I will send the info when I get it. Thanks to everyone for the great suggestions. Anyway, I'm never going to get it until I see it face to face.
