A bit mundane, but worth a post. One benefit that comes with how I paneled my walls and windows is a nice 3" gap. While I had no exact plan, I thought about some insulated panels. One side reflectix, the other side Cordura with some thinsulate sandwiched. Summer you put the reflectix out, winter you point it in. The wife wants privacy this weekend so I hustled up some covers, down and dirty style. I can roll these up and stuff them behind the cabinet gap and they are out of the way.
Some Neodymium disk magnets foil taped to the perimeter of some reflectix for the door windows.
Custom Sharpy Labels to help me figure out what is what. Not a bad fit and finish. This should do for now until I can get the sewing machine out and do them up proper like.
