Many of you may have machines to help you create your envelopes, and if that is the case, then you'll be able to complete this next step in minutes, but as for me, I used the "old school" method of tracing and cutting. For the album above, I made six envelopes, but feel free to make as many as you wish. The album above is horizontal, so I limited the number of envelopes used, but I'm sure it would look incredible hanging vertically as well, displaying a series of these interlocked envelopes.
I began by pulling apart a small envelope, tracing around it on a piece of cardstock, and resizing it so that its center was a little larger than the size of a journaling card. I used the resulting template to create the rest of my envelopes.
After tracing and cutting my envelopes, I folded the flaps and straightened the creases with the help of a bone folder.
The album itself is easy to assemble. With the exception of one envelope (which will be your "lead" envelope), add glue to the top of each flap...
and affix the flap to the back of another envelope, creating a linked effect.
