Just a few days ago I discovered the new jumbo-sized Ziploc bags for storing things like clothing and sleeping bags. These are so nice for some of the stuff I don't have time to put away, are too bulky for Rubbermaid tubs or need to store for just a short period of time in the basement. I think these will be helpful for some of our family vacations as well (packing for eight can be so complicated, especially when we're visiting a number of spots).
I've also found some nice products at http://www.containerstore.com Their velvet-covered CD holders are really nice (especially since we keep our CDs and DVDs in binders instead of the original cases). We keep one near each CD or DVD player and it keeps things safe for awhile. They have hefty-sized lazy-susans and all sorts of goodies. Prices aren't that great and shipping is a little expensive too.
Are there any organizational products or suppliers that you've found particularly helpful?
