Organizing artwork/decorations

[cara1]

I'm looking for a huge portfolio with dividers inside where I can organize the kids artwork/holiday decorations. I have a huge pile of Thanksgiving decorations, Halloween decorations, etc., and they're shoved in the hall closet taking up way too much space. I'm looking for a (cheap) huge expandable portfolio that has dividers so I can divide things out by Holiday. Something like

or

but not as expensive as the ones designed just for kids, because it's really for holiday decorations. The Amazon one looks perfect from the outside, but I called the manufacturer and there are no dividers inside.
Any suggestions on how to organize this stuff? I don't want to just get a big tub, because it's really all paper and I think it could take up very little space if I just figure out the right organizer. Thanks.

it might sound crazy, but my sister uses xlarge pizza boxes to organize her kids artwork. when picking up carryout, they are happy to provide a clean empty xlarge pizza box that she swears works great.

if you found an accordian style system you like w/out the dividers, you could easily make your own dividers by cutting pieces of posterboard or cardboard the same size as the folder system.
