Trying to keep the heat in during winter can be a challenge if you live in an older home. My house has single-pane windows and doors whose airtight seal wore away sometime in the Nixon administration. There are drastic steps you can take to improve your home’s energy efficiency (like insulating and replacing all your windows— yikes!) but this craft project will take you less than an hour, and can cure your climate control problems one window at a time. Plus, you can choose cute fabrics that coordinate with your home. Here’s how I make a draft sock (you may call it a draft stopper), and trust me— if I can do it, it’s a SIMPLE sewing project.
