Business card holder

You can purchase magnets or a strip of magnets that have sticky adhesive on one side and magnet on the other. These can be adhered to a lightweight car holder. Big box office stores sell them (in their catalog) with magnets on them already.

Make a little envelope shape out of sculpey clay, bake it and then add a magnet on the back.

Go to an office supply place and buy magnetic or peel & stick business card holders. I use a different size peel & stick in my embroidery design book. I have about 1,000 designs and have printed the designs that I keep in a notebook, but use the peel & stick for the flash drives with the designs. I also use the 4x6" P&S on my refrigerator for pictures.

I found bag clips with magnets on back @ The Dollar Tree, they will hold several cards. Good Luck!

Business Card Magnets at Staples

Walmart sells magnets specifically for business cards that you can "peel" and "stick".

There are sheet protectors available that are made for business cards to go in binders. Just slide it in like a baseball card! You can put as many sheets as you need to on your refrigerator. This is an example of what I'm talking about: https://www.zerbee.com/Products/Tabbed-Business-Card-Binder-Pages--20-Cards-Per-Letter-Page--Clear--5-Pages__CLI61117.aspx
