Being an avid scrapbooker, I'm asked about how do I scrapbook the odd stuff. Stuff like political buttons, magnets, greeting cards, postcards, brochures, programs and such. Here are a few tips:
The small things that are flat are pretty easy to deal with, you just add them to a scrapbook page. Some of the larger flat items like greeting cards can be a bit more troublesome. First, I do not try to save every greeting card that crosses my threshold, unlike my Grandmother who has hundreds if not thousands that she has saved.
Holiday Cards - I use a square punch and keep just a portion of the card, if it's from an older relative I keep anything handwritten, sometimes I'll keep the front of the card and dispose of the back.
Birthday Cards - I save most of the cards loose in sleeve protectors, including any cash they receive, it's a nice treat for the kids to find later on.
Greeting Cards - I can't fault those who have large collections, this is how scrapbooking really got started before photography became affordable. Folks kept greeting cards they received. In the ashes of my Grandmother's house fire, I was able to salvage 4 bins of scrapbooks, boxes, photo albums, newsclippings and stamp collections. What I was able to transfer to safety rather quickly were her postcards and loose greeting cards. Although both are in varying lengths I was able to store them in photo boxes. That way she can touch them and read what's on the back.

Folded Items: If you can manuever it, place your scrapbook page in a sleeve protector, mark with a photo pencil where you can slit the protector so that the card or folded item can be accessed. Remove the page, insert chipboard, old magazine or cutting surface and use a blade to cut through just one layer of the sheet protector.
