Lifehacker has turned us onto yet another amazing application from Google called SketchUp. No longer is home 3D modeling reserved for the architects and CAD experts of the world. SketchUp allows you to easily put your 3D ideas onscreen and work with the elements of texture, color, and shadowing to enhance your dream home or castle.
PC version only (for now).

Let the spring air flow through your house and listen to the birds sing, while keeping out the bugs and pollen. That's what a screen door will do for you. Here are some sources for building and installing your own. If you are looking for a pre-made door we suggest a storm/screen combo that will allow you to remove or slide the glass down in the summer and replace it with a screen. We particularly like the Larson storm doors as they have retractable screens so there's no need to search and store the seasonal door panels.

You're landlocked, so what. Take the kids to the backyard beach. Here's a how-to on building your own sandbox. Location is a key consideration when planning your sandbox - partial shade is nice but beware of digging near trees and damaging roots. Lowes recommends using cedar as it's waterproof and less likely to splinter.
Throw in a pail and shovel and maybe even a plastic pool and you've got a urban (or suburban) paradise.

What's better than sitting outside, swinging along to some music, and drinking your favorite cool beverage. You know you want to do this - so why not build your own swing now and make it happen. Think of how much more relaxed you'll be.

If your closet looks like this (see above) then maybe it's time you rethink how you organize your closet. With your clothing wedged so tightly, not only is it difficult to find clothes you want to wear but when you do manage to yank them out they most often are wrinkled or damaged from being shoved in there in the first place. Try building this closet organizer and your clothes and significant other will thank you for it.
