I'm a huge fan of the remarkable array of wall decals on the market right now. Rather than re-painting your rooms or investing in expensive original artwork, you simply peel off and apply vinyl patterns in just about any theme and color you can imagine. Presto. You've transformed your space. So where can you find them?

UrbanOutfitters.com has quite the cool selection of hip wall designs, from options that look like souvenirs on shelves to simple rainbow polka dots to organic floral patterns to jungle shapes and animals. Many of these styles can be removed and reapplied wherever and whenever you'd like. Your wallet will benefit as much as your walls, thanks to a 3% rebate from ConsumerClub.com.

I found the perfect kid-friendly wall decals, and a whole lot more for my daughter's room, on ModernSeed.com. The choices are all bright, colorful and a ton of fun. From oversized apples and rainbow butterflies to funky cars and old-fashioned airplanes, it's all here. You won't believe all the other incredibly well-designed, minimalist products on this site. There are books, toys, furniture and a whole lot more for kids' rooms and grownup spaces alike.

And now for the granddaddy of all wall decal companies — and perhaps the best selection on the web: WhatIsBlik.com. The options here include shapes and designs by famous designers like Charles & Ray Eames and Keith Haring. But there's also plenty in the "Blik Graphics" category too, including spheres, paisley, flying birds, aliens an much, much more. Order many of Blik's designs on HomeDepot.com and get a 2% rebate on all your purchases.
