I have a tendency to keep all of the cards people give me for birthdays, holidays, etc. I guess I'm just sentimental :) But all they do is take up space, so I decided it was time to make myself get rid of them, but some were just so pretty... So I cut them up and made them into bookmarks and "laminated" them so they don't get all grubby.
First pick out your card. This one is made with paper that is pretty all the way through, instead of just the front cover.
Cut two strips off, making sure they are about 1/2 an inch less wide than your packing tape. One will be your front, one the back.
Cover One piece with shipping tape. Make sure there is tape hanging off of each edge.
Do the same for the other strip.
Very carefully line up the two strips (better than in this picture lol) with the sticky sides in.
Once you have them lined up, press them together. Press the tape together.
Lay them on a flat surface and use something like a credit card, or the nonsharp side of scissors to rub the tape together and remove any air bubbles.
Trim off the excess tape, and you're done :) Its alot cheaper than buying a laminating machine, or even some book marks, and you can keep a piece of your memories (lol sorry for the corny-ness)
