My sewing table is set up facing a window, but it is about 3 feet from the window. I like that I can drape over the front edge of the table when I am sewing to keep the fabric flowing. I like that I can walk around my table so that I can get the dust/fabric snips and threads off of the floor easily with a swiffer dust mop.
I like looking out the window from time to time to rest my eyes, and to watch our resident wildlife (our house is in the middle of woods)
