Here's what you need:
1 piece of exterior fabric 5" x 9.5" (interfaced)
1 piece of lining fabric 5"x 11.5" (this is also the binding & lining for the exterior pocket)
2 pieces of fabric (same as lining) 3" x 1.75" for tab (interfaced)
7" zipper (you could use a 6" zipper or larger, but this is what I had)
snap, button, velcro (we'll discuss this later)
It would be nice to have:
self healing mat
Take your binding piece, fold in half, press, open up and press raw edges toward crease. Press.
Now onto the fun part! Ready?
