The technique demonstrated on Day 17 was how to use a grosgrain bow as a "tab". By carefully placing the bow and then strategically placing another object over it so that only a small portion is showing, the bow appears to be a little pull tab.
I decided to use a family photo as well as photos of my parents when they were first married and then from a few years ago.
You can see the little red tabs sticking out from behind the photos. If this was a `real` page, the little tabs could be pulled to reveal a journal entry hidden behind the photo.
