Those are the best kinds. I make up patterns as I go too.
I was especially intrigued with the red print circles in the body of the quilt. Now that I have looked closer at them I think they are half circles appliqued on to the yellow wide strips. However you did them it turned out to be a great variation on the quilt.
You are about to have some very happy little ones in your world when they get their quilts.
