I did 8.5 x 11. However, most printers and copiers need margins of at least .25 inches. I found that out the hard way. So, leave yourself some room around the edges.
I copied onto plain paper, and put them in a nice report cover, with a clear front, so they could see our cover.
I did ours by hand. I'd choose by hand over a photo web site any day, personally. If you're at all into digital scrapbooking, you can try Memory Mixer or Adobe PhotoShop Elements. However, if you're used to scrapping by hand, then you should go with what you know.
You may have to make A LOT of copies, so I say go with plain paper in a nice report cover. Easy to part with, but still well-presented.
Hope this helps!
