Making a Hipster Whiteboard couldn't be any easier: simply cover a 3x5 index card in Scotch Packing Tape and you're done.
To complete the setup, I added a tiny whiteboard marker I picked up from Target recently for $1.00.
Will it be useful? Don't know. I can imagine it would be fun for a kid to play with. And I do love my whiteboards of all sizes. So it's a resounding maybe.
Perhaps I should apply a layer of tape to my tablet, so I can use it as a whiteboard? That may be useful for sketching ideas out at my desk.
