I just finished the binding on two of my Christmas quilts. Neither is in baby or child fabric but both measure as squares roughly 43 x43 inches (one is a bit bigger: 43 3/4 x 43 inches). The first one is the Christmas quilt with feathers I showed on my prior post:
The second I chose to free-motion loops throughout.
My 8 year old daughter, Izzy, has decided the Bear made a very good model, though next time she would like to pick the stuffed animal to use.
