This is a little project I taught at stamp club a few months ago.
When you slide off the band, it opens the tri-folded portfolio.
It reveals 3 pockets (created out of 3 business-sized envelopes trimmed and decorated) that swing open like pages in a book.
Each pocket has a tabbed card that pulls out. You can put photos, recipes, love notes or journaling in each pocket.
I got the idea online here. She gives great step by step directions.
