Hi, we are getting a cushion for our rectangular reading nook. The rectangle isn’t perfectly symmetric - it’s about 3/16” deeper (from wall to overhang) on one end vs the other. We are wondering if it is best to have the cushion (a) exactly to the edge on one side, and protruding 3/16” over the other, (b) exactly to the end on one side, and set back 3/16” on the other, or (c) something different like recessed or overhanging on both sides. Any advice would be most appreciated!
