I don't really understand the whole scrapbooking fad. Stores are popping up in every strip mall that cater to scrapbooking. They sell everything from overpriced photo albums, stickers, stamps, ribbons, etc. all for the sake of creating memories.
For most of my life, I have kept my own version of a diary/scrapbook. They include my journal entries, sketches, notes, lists, plane ticket stubs, stickers, stamps, old letters, postcards, you name it. I have never had to go out and purchase special scrapbooking equipment. Just a journal a pair of scissors and some glue. The rest are found or already aquired objects.
I have also never been pushed out of my home by scrapbooking material. I see homes with a special "scrapbooking room" full of purchased items for making books. The thing is, the clutter gets to be so overwhelming that there doesn't seem to be any time for scrapbooking at all.
If you enjoy scrapbooking, a system is necessary for keeping your materials clean, organized and off the floor. About.com has a great list on how to organize scrapbooking supplies.
Keeping your supplies well organized will also help you save money. You will not have to rebuy or stock up on any materials that you realize you already have.
