I had bought some frames on sale at Michael's probably about 2 years ago-- I had hung them on the wall and filled the smaller frames, but didn't have anything in the 11x14 frame.
I decided to do a collage of photos from our wedding from the photo studio. I used Microsoft Office Publisher and it took me less than an hour. I inserted a bunch of the pictures and then just started making them different sizes. I would also crop some of the pics where there was dead space. I just worked my way across and down the page to keep filling it in.
I took it to Office Depot on a flash drive and they printed on 11x17 glossy, thick paper for only $.49! What a steal! Walgreens and most photo sites wanted at least $9.99 to print. I have another 11x14 frame to fill, so I'm definitely going to put something together and get it printed there.
Here's some pics of the finished product:
