Make a “shim”.
The More & Co. business card was created on heavy duplex paper, making it an effective shim. A shim can be used to fill in a gap of some type, prop a door open or balance a table when eating a meal out on the town (our personal favorite use).
(Note: “shim” is also one of the names a certain someone at More & Co. occasionally goes by.)
Thanks to PFlow for showing us his use of a More & Co. biz card as an effective shim.
