Perusing Pinterest the other day, I came across this vintage tablescape from Oh So Beautiful Paper that had an unusual, whimsical table runner made from old black and white photos. I love how the photos cascade onto the floor! Not only is this a practical and creative way to incorporate vintage pics, but it's also easy to re-create and can be adapted for different themes.
Flea markets, garage sales, and antique shops always have boxes of old postcards, photos, and other paper goods, so gathering the supplies is affordable and relatively simple. I'd take a narrow strip of butcher paper and start affixing the photos from the center out. Use double-sided tape and be sure to completely cover the paper so that it looks like the photos are just scattered on the tabletop. Depending on how dramatic you want to go (and how many pics you have), you may want to keep it on the table vs. piling the photos on the ground. For a bon voyage soiree you could use postcards from tropical locales, for a bridal shower old wedding pics, or for a game night it could even be crafted from playing cards (a little Alice in Wonderland, don't you think?).
