Longtime readers of this tips newsletter may notice we collect clever folding templates. So when we stumbled on the Letterfu website, we knew it would eventually show up as a creative tip. (Past paper folding tips include pocketMod guides, or our collection of paper Mac templates.)
Basically you print a Letterfu design on a sheet of paper, write your letter on the back, fold it up, stamp it, and send it. The letter becomes its own envelope. It holds itself closed, secured by the stamp – so it doesn’t even need any glue. You use the entire sheet of paper, so there’s no cutting.
