I googled quilt barn then clicked images. There are so many barns in the north with quilt blocks on the front of the barn. I am slowly working on a wall hanging with quilt blocks on barns. Slow because I mislaid some of the blocks that are made:(
So happy for you and your quilting shed looks fantastic. We have indoor electric heaters we use in rv. We just pick them up at Target or hardware store. We get those that auto cut off if tipped or unlevel for safety.
