When a vacation was chock-full of Kodak moments, why not combine a few snapshots into one frame? To accommodate any number, size, or arrangement of photos, your best bet is to customize a piece of mat board yourself. No tape or glue is involved — just a few photo corners — so the images can be easily replaced with your new favorites.

What You Need

Mat board, cut to size (about $6.50 for a 32-by-40-inch piece, art-supply stores)

Cork-backed metal ruler (about $7.50, art-supply stores)

Xyron self-adhesive photo corners $3 for 500, www.dickblick.com)

Self-adhesive spacers (about $6.50 for five feet, framing and craft stores)

Utility knife (about $6.50, art-supply stores)

Frame (prices vary, art-supply stores)

How to Frame It

Step 1: For the look shown here, use a cork-backed ruler (to avoid scratches) and position four four-by-six-inch photos faceup 3 1/2 inches from the outside of a 16-by-20-inch mat board.

Step 2: Apply self-adhesive photo corners. Leave each corner a sliver of breathing room so that after you slide in the photos, they won’t buckle over time.

Step 3: Cut a spacer the length of one side of the glass with a utility knife. Attach the spacer flush to the glass edge. (It will disappear under the frame.) Repeat for the remaining sides.

Step 4: Flip the glass over so the spacers provide a buffer between the photo’s glossy finish and the glass, then pop the whole shebang into a frame.
