I cut one end off each envelope and the envelopes with pp from Cosmo Cricket, preserving the windows. I created a tag to fit into each envelope. I added some canvas pennants from Maya Road as additional pages and created covers from felt.
I covered the large envelope with additional pp and used buttons and bakers twine to created a clasp.
Thanks to Lessology and Gauche Alchemy for the inspiration!
Have a great day!
