I admired this quilt when you posted it on VQW. It is fabulous. I really love how you quilted it. Outlining all the Geisha and flowers in the fabric print is very labor intensive, I know I did the same thing on one I am working on. There is very little to no fudge factor, you have to hit those lines pretty much dead on. The results are so worth it. I did mine with monofiliment, more forgiving if you miss a line.
Your cousin should be very happy with this. Hope she appreciates all your hard work. Sounds like a nice collaboration between you and your mom.
