Temporary Extension Cord Protection - If you're having a party or some other event in the yard and you need additional electricity sources, here's a great way to keep extension cord plugs dry. Cut notches in the opposite sides of a reusable plastic container and snap on the lid. Your plugs will stay dry if it happens to rain or the ground is moist.
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 won't be going anywhere.
