Below is a semi-inspiration picture...
We opted to cut the chart up across 5 picture frames, with the names listed in alphabetical order. Final product below:
Would it have been cheaper to do the traditional folded pieces of paper? Probably. But in the end, this wasn't really expensive, either.
5 picture frames: 40% off @ Michaels, and used a 25% all picture frames coupon: $12
5 4" black easels: $14.99
Blue backing paper: FREE (same as used for the envelope lining)
Time, labor, effort: FREE (though I should probably charge for my services!
Even though it cost around $30, I know I'll be able to reuse all the black frames in my house when we're done (probably for wedding pictures!), and I can probably re-sell the easels, too!
