So I came up with this idea to use a business card or a cancelled credit card or the sample cards that come with the pre-approved offers. Of these, you can always find a business card in your wallet or in your laptop bag.
For this instructable, I will use a cancelled credit card.
1. cancelled credit card or a used gift card or a business card
2. Ruler (optional)
3. pencil or pen (optional)
4. small rubber band (optional)
Step 1: Mark and fold
2. Use the ruler or well defined edge of a table to fold the card at the marks lengthwise.
