Sashiko Template w/ Box

A friend of mine asked me to remake a ripped paper Sashiko template, and I was happy to help. Once I finished, I figured they'd probably want a place to store it so it wouldn't get damaged again, so I designed a box to go along with it.The original paper template had notches on the sides. I wasn't sure what they were for, but I included them in the remake and work them into the box design too. I'm not really into embedding magnets into my print (and I didn't have any on hand anyway), so I designed grooves that let the box stay closed with rubber bands. If you're in a remix move feel free to take the design and run with it.Happy Sashiko'ing!
