Keep your heating bills low and your house cozy with a Draft Snake! They measure 20" long (for doors) and come with instructions on how to shorten them to fit your windows, they're filled with lentils (which
overlap for maximum wind-stoppage) plus a bay leaf for
luck and to keep bugs out of your house... And, if that wasn't enough, they come in many adorable colors/styles... but The Hipster (pictured) is my favorite! $7.50 at OhTheCuteness.
