I used a darker grey print fabric on the back.
I had so much trouble getting the measurements right!! Things I'd do differently if I were to do it again:
- Do an envelope-style opening on the back (I hand sewed it closed)
- Have Spoonflower (who printed the fabric) center the heart on the fabric - the image wasn't positioned very well, and I had to guess about where the heart would show up
- add piping or a ruffle around the edge
I'm very pleased with the outcome, though. Now I have to find a box and ship it up to Maine for her!
