This picture shows one of the envelopes. I didn't want anything bulky so I used tags to label the envelopes. I used a punch along the flap of the envelope to decorate it.
And here is a picture of the front cover. Because I was trying to keep it from bulking up, I didn't used anything to seal the envelopes and so I used a ribbon to hold the booklet together. I used a 3/4 inch wire which is holding 12 envelopes and 2 covers made from book board and paper.
