quick mini useful thing how to:
Command Interlocking Fasteners (like velcro, but not)
Starbucks gum tin (sorry ’bout the branding, only tin I can find with this shape) (Angela wrote to tell me Eclipse mints have a similar tin, and it’s a little larger)
put one not-velcro thing on the back of the tin, and another on the inside of a desk leg*
handy under desk, easily reachable, temporary, removable pen holder thingy
* Or the side of your computer, or printer, or monitor, etc.
