Probably the album anniversary quilt for my parents. It's completely hand-quilted but machine pieced. They were thrilled and I loved doing all that quilting for my Mom and Dad :) It was a labor of love that I would only do for them or my kids.
The most expensive was a Jinny Beyer 12 month quilt class and all her fabric. Yikes! And I'm not even done. I really love it though. Probably will machine quilt it or have someone else long arm it. Still not done spending on that one lol
