I used insulation foam boards, cut into 15"x15" squares. Than I covered each with batting and fabric using duct tape. To hang on the wall I used double-sided velcro so they can be taken down to clean, or rearranged. It really made this drafty room so much warmer.
Wow that is really cool and unique. Just wondering about the grill - does it being attached
make it harder to clean it out? And what abt when it's time to replace it? I love how it's attached to the railing though - perfect height for grilling, and it doesn't take up any of your precious entertaining space.
