You may want to search The Henry Ford's Quilt Index to see what others have done in the past. Every yo-yo quilt I have seen does NOT have a backing. However, I think a backing would make it more durable.

Here's a link to The Quilt Index: https://quiltindex.org/search/quilts/

I am very impressed by Yo-Yo quilts. I would never have the patience to make a whole quilt out of them.

:) Hi ,
You may find ideas in the post I made on what to do with yo-yos if you find you don't want to invest the time to make a quilt.
