Announcing Cotton Spandex Jersey!
All by itself, with just some stuffing and stitching, this could work as a cheater quilt for a large scale doll (such as American Girl).
The wallpaper version of this design is in a much larger scale than the fabric version. As always on Spoonflower, design sizes are customizable for each purchase. One can even purchase the same design in multiple sizes (though that takes a little co-ordinating with the artist. If interested in doing that, I can explain how).
What we do and how we do it.
