Good old Martha taught us that rather than buying those ridiculously expensive anti-slip mats for a rug, just turn it over and run a few lines of acrylic-latex caulk every 6 inches or so. Let dry and flip over and your rug wont be going anywhere! genious.
Separate your wall colors. This is SUCH a good idea!! I dont like two colors coming together on a corner and this is the fix for that! This would also be a great fix for the beat-up corners in the house. Such a good fix for older homes!
