We are having some crazy cold weather in East Tennessee which means the power bill is going to be even more crazy this month. I made a draft-blocker to help keep the heat in. It took me about 15 minutes to make and isn't too much of an eye-sore. Made from reused pipe insulators (from a homemade water slide) and an old throw blanket, this was cheap project that will hopefully save us some cash!
This could actually be a no sew project since the pipe insulators have slots down the middle to stuff the fabric into. I went ahead and sewed ours though since we let Hank in and out about 50 times a day and needed something more sturdy.
