It's just beautiful. Did your granddaughter know that the fabrics she selected were for her b'day quilt, or were you being secretive? I LOVED purple at that age (had a purple velour bedspread, which was wonderful until the cat peed on it near the pillows and left a big crusty stain, but I digress). I maintained my love of the color as first choice till in my 40s. You have made a treasure for her that she will adore forever because of your love, even if purple someday is not her favorite color.
