Ok, now this is my idea, suddenly reallised how I could store and use up some of the cardboard boxes that I seem to collect by the handful.
I cut open a Coco-Pop Box, and made an envelope form it. I added 1/2 " to the width of my stamps, to make a nice fit, then added about 1" for each flap of the envelope.
I also added an extra inch to the depth of the envelope so I could cinch some holes, which I am going to add my binding to, I want to use to rings that open and close so I can add more envelopes as I make them.
Here's the sealed envelope.
With my stamp sheet inside.
I've left the outside blank but intend too label it with what is inside, also thought I could stamp images when I take them out to use next time.
