Envelope Note Pad
Ever wish junk mail became more useful? Perhaps make a Pocket Note Pad out of them. A brand-new legal pad seems wasteful and or a cute grocery list magnet is always over priced.
Instructions are easy, a few snip of the scissors, a wrap of the rubber band and BAM instant presto, Pocket Note Book. Supplies are: old mail envelopes, one rubber band and scissors. Demo is below in reverse. Remember to recycle when all finished.
Take a look at the finished product! Sharpy shows up very easily on the inside side of the envelope or just stick to the blank side.
