Coffee platform for Ikea picture ledge

I got the Mosslanda picture ledge from Ikea. Put it behind the couch, it makes a great shelf for things you need to reach for - no need for a coffee table or end table! Only problem? My coffee mug is too big around to fit comfortably.

Does this sound like you? Is this exactly the problem you're experiencing, today and every day? Worry no more. Here's a little platform that will hold your coffee mug in stable position above the lip of the ledge. It even has a cute cursive little label on the front to let you know this platform will only work for coffee and no other beverage.

Prints great upside down without supports.
