To pull together the miscellany of summer, try sorting your smaller, more lightweight mementos in the clear pockets of a slide sleeve. This playful version of a shadow box can be tacked up just about anywhere or hung like a mobile to let the sun shine through. It's fun to showcase a mixture of the bought and the found. (Bonus: slide sleeves are cheap! We bought four for less than $2.)

We chose a slide sleeve with pockets measuring 2 by 2 inches. In that size, you can easily fit:

• Small souvenirs
• Ticket stubs from parks or theaters
• Bird feathers
• Decals and stickers
• Pine needles, leaves, dried flowers
• Cropped photos or postcards
• Map fragments
