Someone, at some unknown point in the past (probably many decades ago, considering the types of fabric) spent a lot of time hand sewing the blocks, with dreams of a beautiful, finished quilt, and then probably gave up when they saw the problems with it. I suspect that someone else, at a later time, added the ghastly yellow sashing, since that work was done with a machine.
Once the garish yellow sashing was removed, the blocks looked better.
This will be the third abandoned quilt I have "rescued," and it's the most hopeless. A close look at most of the blocks reveal that I will lose most of the points. I will see what I can do, and will just have to live without points.
