There is no need to frame all your photos. By using clips (can be picked up at Aarons Brothers Frames and Michael's Craft Store) a homey effortless feel is displayed. In your office you can clip up destination postcards you have collected over the years or old photos of grandparents and great-grandparents can be clipped on your bedroom wall. If you don't want to nail several clips into your walls, you can always hammer in two nails approximately three feet apart and wrap one long piece of wire from one nail to the other. Attach your photo collection with small clothes pins. As much as I love old frames, this look is much cheaper and has edge. Just remember to not overwhelm the eyes by posting too many--choose your favorites!
