I've been collecting used mailing envelopes from a few different sources and recently realized that the collection had grown almost out-of-control. I save the envelopes to make journals, where the envelopes are used as the pages. With my current supply, I was able to make seven journals, with some envelopes left over. So I started with stacks and stacks of these:
And finished with these:
The covers are decorated with various bits and pieces saved from old mailing materials, like this one which uses a green security pattern for the decorative paper embellished with some clipped postal marks and stamps from Japan.
Or in some cases, the embellishments are printed directly onto the envelopes, like this junk mail sweepstakes example.
And all of them have envelopes for pages, with all the security patterns, plastic windows, and stamps in tact to make for a very interesting journal-keeping adventure.
Available in the "Recycled Journals" section of my Etsy shop!
