Printouts from the attached PDF or Powerpoint file
Print out the sheet or sheets you need and cut each wrapper out more or less precisely along the outer edge as shown in the yellow note box in the upper right corner of the picture.
Step 1: Fold
Step 2: Align and Tape
That's it, the wrapper is ready to use. Open it up, stick a finger in one end as a stopper, put coins in. The shaded area is the height of the stack. Fold over the ends. Take to bank.
My printer is pretty accurate maintaining the actual dimensions laid out in the powerpoint and PDF files, but if you find your wrapper is a bit too tight leave a little gap when you align the edges for taping. Overlap more if it seems a little loose.
