C+P Handmade Envelopes

This is going to be a relatively quick swap for 6 handmade envelopes to each of 2 partners. In the end, you'll have a dozen interesting envelopes to send happy mail in!

Envelopes must be a mailable size (no minis) and ready to use. You can vary the sizes, or make them all the same size. Make them interesting by reusing things like calendar pages, take-out menus, maps, sturdy book pages, etc. No repeats, please. Patterned scrap book paper is allowed, but is limited to 2 envelopes per set.
