It turns out that I did not stop at 20, but have 23 blocks made. I must have got really confused, and forgetful. There are two blocks in this quilt, that are almost identical ----but not quite....blocks 23 and 25. Would you agree? Looking back over my blocks, and the saved copies of patterns, it looks like I have block 23 but not 25. Seeing how I have only 2 to go (plus the border!) I figured i might as well keep going.
Would anyone be prepared to share their saved copy of block 25 with me? Or is this really bad manners?
My other option is to choose the 20 that I like the best, and use the 3 extras as cushion covers.
