Oh, my! Look at you! Coming right along!
I just used whatever fabric was to hand, or this and that. Mine are all quite a hodgepodge. After awhile, I laid them out, like you, and took a look at the color composition, and thought where is the yellow?
When QNS offered us some scraps when she was cleaning her sewing room, she sent me some yellows. I'm so glad to have them, after realizing what a dearth in my stash I had. They are so cheerful-- and special too because they were sent to me by her. (You know, when you see the fabric in the quilt, you remember what dress it was originally, or remember where it came from, etc.). I decided to use the yellows for the Bonnie Hunter Mystery quilt as she mentioned yellow, but your post puts me in mind to use some of ONS's yellows for my remaining FW blocks.
