Paint the wall in flat color then use the same color but in high gloss for the design! LOVE this idea!!! (This is one of those pins that I didnt re-pin the first time, and then couldnt find it when I wanted it... until now!)
Use foam gaskets to seal electrical boxes - According to energy experts, electrical boxes that hold switches or outlets are major sources of heat loss. Foam gaskets ($3 for a pack of 12 at home centers) won’t completely seal the boxes, but they’ll help. They’re quick to install— just take off the cover plate, stick the gasket over the box, then put the plate back on.
