Lay the bag flat and fold it about ¾ of the way to the top.

Tear off the proportionate size tape and place evenly over the bag, starting at the bottom and working your way up towards the zipper, leaving a little bit of overlay along the sides.

Once you've taped up to the zipper, turn the bag over and fold over the edges of the tape.

Now just like you did the front, place the tape on the backside--it's okay if it over hangs on the edges, you can fold them over, or cut them off very carefully.

If you want, grab a hole punch and some ribbon. Punch holes along the side (if planning to put into a binder, line them up according to the spaces between the rings.)

Fill with your bag with makeup, colored pencils, glue sticks, or whatever tools you need to keep handy.
