I think the reason you are not happy with the OBW is because of the coloring. They need large areas of different colors. They are fun. Next time get a fabric with more uneven coloring over the fabric. The OBW needs sloptges (technical term LOL) of color here and there.
I like the way you did the borders on it, and I think your borders saved the quilt and made it interesting. I loved seeing your other quilts too. You do have a talent. I hope to see more
