Talk about a Mystery Quilt!

While looking for a box to mail a quilt back to a customer, I found a box on top of a shelf and was a bit surprised when I opened it and found a partially finished quilt I had started several years ago. I figured I'd just toss it, but found that all the large border was done, 2 of the 4 rows of blocks were done and many of the other blocks pinned and ready to sew. There was a bag of squares cut and ready to make 1/2 square triangles. I now have all the blocks that were pinned sewn together and was having trouble understanding why I had stopped in the first place and put the quilt away. Then I discovered I do not have enough white but I think I can find something close enough. I am about half a dozen blue triangles short, too. Perhaps that was the reason or perhaps I just got overwhelmed with trying to put this puzzle together. I took a couple of hours to figure out where the pieces go and what pieces were missing. All the pieces were in a wad, all wrinkled up and it took quite a bit of ironing. The quilt will be 108 inches long! Perhaps I just had got tired of piecing such a large quilt. Who knows? I do really love this thing, though and am anxious to finish it up. The bottom picture is what I have done and shows what pieces I have missing.
