OMGoodness what a tremendous family heirloom. I absolutely love Dresden Plates.
The biggest issue in my family would have been 'sharing' this wonderful quilt now that it's completed! Your granddaughter free motion quilting took my breath away showing such talent at just nine years of age! Incredible! Her eye in choosing just the right colors for the sashing and eye 'popping cornerstones' is far beyond her years. I'd love to borrow her to help me with color choices :0)
I believe the puffy stuffed Yo Yo's are what our British quilting friends call Suffolk Puffs.
