Photo table numbers

Another great idea from Martha Stewart Weddings

Take photographs of you and your groom holding up numbers and use them as your table numbers. Print them in black and white so they dont clash with your flowers. You can use different poses for each different number.
For something a bit different, try dressing up as different characters for each photo

Photo wall with a difference

From Wedding Obsession

Set up your own picture station with a laptop, digital camera, and photo printer. Have a friend or hire someone to man the booth. Pose, snap, and print! Consider setting up rows of string like the picture above and hold the snapshots with butterfly clips. The photos will be ready to go when it’s time for the guests to head home.

Or, if you prefer, use the ‘clothes-line’ idea to put up any pictures of you and your groom (baby pix, when you first met, first date etc.). I’m sure it will be a great alternative from the usual slideshow presentation.
