Line It With: A strip of pretty paper displaying one of your favorite snapshots — or a row of them. (Note: This idea works only with straight-sided vases, not ones that taper.) Measure the inside height of the vase, then wrap a string around it to determine the circumference. This will tell you the size of the piece of paper you'll need. Cut the paper a bit longer than the string so there's overlap, roll it into a tube, then slide it into the vase to confirm that you have a perfect fit. Next, take the paper out and attach the photo (or photos) with acid-free double-sided tape. Slide the paper back into the vase, and use a little piece of regular tape on the inside to secure the paper where the edges overlap. Presto!
