I buy these at Archivers - they are wonderful for storing patterned paper because they don't have hinges - its easy to get things in and out of them. They are not great for taking places, also because the lids are loose and hard to keep on them without the hinges and buckles.
But for scraproom, it is perfect. They are broken down into the types of papers I use the most - Upper left says INternational for International travel papers. Upper right is USA Travel. My husband is a license plate collector and I've actually accumulated a lot of pages with license plates on them.
Natural papers have straw, grass, bricks, wood, or anything else like that. Even pages of sand or rattan.
Tropical is beach stuff and fish stuff.
Cruise is cruisehips stuff and pages that simulate water or waves, like blue swirls or bubbles.
Textured is stitched papers, embossed, glittered - anything that has a feel to it.
Food is BBQ papers, restaurant papers, die cuts of silverware, and even papers covered in cookies, cherries, corn on the cob, fudge, pasta, or anything else edible.
One is marked travel - that is plane stuff and car stuff and general travel things.
Three of them say MISC. for dots and strips and misc. patterns - things like that.
The bin in the lower right is my cardstock scraps.
