Thanks Emma and Magpie. OBW stands for One-Block-Wonder.... it's a quilt where you cut up a 6-layer stack of fabric and make hexis. Then, you arrange them and sew them back together. I started this one 6-7 years ago and put it aside when I moved back to Michigan. It's not my usual thing and found it very frustrating..... but now that it's done.... it really lets me relax and concentrate on other things. So, it wasn't so fast to finish.
