Maori design in funky orange. You can use it as a template for your own envelopes. I have sent these in 'real life' through the postal system. Looks okay in black and white too. Print up a batch as a gift.
You just need scissors and a glue stick (and the printout of course!). Good for mail art crafts, or to use as pockets in paper-craft or altered art works. Password is 'orange'.
