i used a green walgreens reusable bag.
This is very handy for ID cards in school or work!
•Straps from the old bag
•Tape or sewing kit
•Lanyard clip or key ring
Step 1: Step 1: Taping
and tape or sew secure.
Step 2: Step 2: Adding the Clip
this might be hard to understand ,sorry.
Then, secure the taping with more tape.
Or sew a small pocket for the lanyard clip.
Step 3: Step 3: Testing
Swing it around a few times hit it lightly on the wall
then add the card and see if the lanyard clip falls off
if it is still in shape then you can use it!
