Things You'll Need
- Weatherproof shipping envelope
- Double sided tape or strong glue
Over time the black bar on your credit card can become worn down. The raised numbers and letters on front will be buffed down, and the ink on the card can become unreadable. A sleeve will help to protect your credit card from becoming worn out. Your bank may not have sleeves to spare, but you can easily make your own at home.
Purchase a Tyvek or other weatherproof shipping envelope from your local office supply store. The material these envelopes are made of is similar to that of standard credit card protection sleeves.
Cut out a rectangular piece sized at approximately 6 3/4 by 3 inches. (A standard size credit card is 3 3/8 by 2 1/8 inches but the envelope should be bigger.) Lay the piece in front of you in portrait orientation (the longest sides should be vertical).
Cut out the two bottom corners of the rectangle—the size of each corner that is cut should be about 3/8 inches wide by 3 3/8 inches tall. Use a pen or thin magic marker and a ruler to outline the corners to be cut for accuracy.
Fold the bottom flap up so it lines up with the top half. Use your fingernail to crease the bottom and create a permanent fold. You should now see two outer flaps (right and left).
Place a thin strip of double sided tape or strong glue on the two outside flaps.
Fold the flaps inward and press them into place over the top center flap. Crease the two side edges with your fingernail. You should now have a pocket that is similar to a credit card sleeve. Let the credit card sleeve sit and dry for an hour before inserting a card if you used glue.
You may have to do this a few times to get the right size sleeve to comfortably hold your card. You should be able to cut about 12 sleeves from one 10 by 13 inch envelope.
