I am backing each block with the same fabric as the front and as you can see I have basted each 5" block to muslin to save fabric. I baste two together and then add the muslin which I use over and over again. I quilt all my quilts (even king sized) on my 1988 14" hoop.
I know I should be cleaning and decorating for Christmas, but we will have another Christmas next year and I only plan to make this quilt once. And... I have to keep it up because I am itching to start on the next three pot holder quilts whirling around in my head. Enjoy the day.
