These little boxes come together without having to sew sides to a bottom. Give em a try and see whatcha think! *If you're on the newish side to sewing vinyl, make a bigger box. I'd suggest 15" squares with 4.5" boxed corners. OR you could opt to do a drop-in lining. (To me it's annoying, just sayin'.)
What you need:
Two 10" pieces of fabric
One 10" piece SF101 interfacing for lining
One 10" piece By Annie's SOft & Stable foam interfacing
