I’ve been in love with maps for as long as I can remember and a little while ago, I decided to create envelopes with maps on them. The result is visible above. The envelopes are all made by hand, and I have a few different sets available for sale on my website.

I remember the geography library at my school had a table full of free maps out front of the door. I would imagine these would be a pretty sweet, and pretty easy, DIY craft.
