I started looking around on Amazon, Ebay, etc. and then thought to myself "what are you doing - just make your own!" Which is what I did.
Canvas cut to 7.5 x 13.5
Sharpie oil based marker - love these markers!
When paint was dry, fusible webbing sandwiched between canvas and silk remnant cut to size
trimmed piece to 6.75 x 13 - marked center and 3" from each end; straight stitch over the lines
zigzag stitch over short ends
folded the ends at the 3" marks, pressed crease with steam iron
zigzag stitch over raw edges
insert checkbook and register
I'm very happy with the way this turned out - took about an hour in total to do and didn't cost a cent!
