Quick Fix: A Pocket Square

I've had trouble finding linen pocket squares in stores (I don't want to buy one, sight unseen, from the Internet).  Exasperated, I tried a plain, heavily ironed white hankie.  But it was way too much material.  So I cut it in half and refolded it with the ragged edge at the bottom, then tucked it into my jacket pocket.

Not perfect, but definitely sharp.
