Perfect timing as I just made my first one of these yesterday! I was giving my new Brother SQ9050 a workout (it passed with flying colors, btw! I do need a 1/4" foot though because I am hopeless!)
Anyway, I'm looking forward to everyone's answers, although I really like the idea of just "improvising" and hiding hearts, words, etc. all over in the quilting.
My father will be starting kidney dialysis soon, and the quilt will be for him so hiding messages of love and support in the quilting really appeals to me right now.
