Benjamin Franklin's Folding Paper Ink Tray
I've forgotten where I heard of this one, but my idea is Ben Franklin invented this as a disposable ink tray in his printing business. As a printer he probably had his fair share of scrap paper to use up. I can't find anything on Google, but if anyone knows whether Franklin did invent it, or who else did, please let me know.
Its not essential, but a square gives good final proportions Crease lightly down the middle to give a centre line
Creased, unfolded, then fold the corners diagonally
and pinch the corners to make them stand well. You can crease the ends to help them stand too.
