Even though it's geared toward people who own a home, I've found that the Not-So-Big House series by Sarah Susanka has some great ideas to encourage the small-living line of thinking.

Also, while Ikea is awesome for storage and organizational needs, be careful that you're not spending in excess of what you need! I'm very guilty of that because I go in and think "Oohhh! Neat - I need that to store this" when I already have a suitable storage solution for that item, and am just seduced by the new and pretty ideas Ikea has to offer.

ReadyMade, RealSimple, and other similar magazines can offer many inexpensive ideas for home de-cluttering. Save money and stop by your local library for back issues, or scour your local book resale shop for old copies of these magazines, usually at half price or less! Then share your copies with friends!

Having said all that, home organization can be fun and creative! Good luck!
