First I had to haul out to Home Depot which is on Stone Church Rd. here on Hamilton Mountain. It took me two buses and both were long trips. I got a long piece of MDF (Medium Density Fibreboard) for around $8 and I got a guy in the lumber department to slice it in half. He assured me I could carry both pieces back home on the bus but I knew I couldn't, so I left one of them there. I was told that all scraps get donated to Habitat for Humanity so I felt OK about paying for it and not taking it home with me.
Then when my husband and I were at the Ottawa St. "Sew Hungry" food truck festival I went back to the fabric store I went to with C two weeks before that, and got this really groovy chevron-patterned fabric. I also got 2 layers of batting (the stuff you use in a quilt) and used J's staple gun (and her help!) to staple it all down. Here is how it looks from the back:
