Oh what a lovely yo yo quilt.
In summer I sent out requests from family and friends so that I can make one using the yo yo maker. Oh how easy that makes the yo yos. I wondered what to so for the sides as the only alternative I had seen until this time was to make xes out of light fabric and finish lining it up with Vs on the side similar to what this look like. As I really want to get started putting it together soon, I will do the sides like your great find. Oh, what a lovely keepsake.
Mine is all sorts of fabrics including darks although I started out with all lights and mediums. What family sent is an assortment of fabrics including holiday fabric.
I want to keep record of some that each sent.
