2. Use dimensional adhesive between layers of paper (or photos) to make a space for your journaling tag. In addition to making space for your tag, using dimensional adhesive (as seen below) gives your tag a nice "slot" to slide into and out of.
3. If you want people to read the journaling, include some sort of pull tab so that people have something to grap. Ribbons, twine, paper clips etc. work well.
4. If you want people to read the journaling, make it accessible without removing the page from the protector. Either have the tag at the top of the page or carefully modify the page protector.
5. If you don't want people to read the journaling, downplay the tag in your design.
6. If you want to record the story, but you don't want anyone to have easy access to it - include it on the back of your layout!
I hope this inspires you to use hidden journaling on your layouts. Do you have any tricks of your own? I would love to hear them!
