Some of us at our church made mug rugs for table favors one year. Two 5 inch squares with pinked edges two pieces of thin batting and a few whole cloves, a piece of cinnamon stick and whole nutmegs inside, made a sandwich of them, then pounded the spices with a hammer to smash so they would smell good. Still do and I use them, the heat from the cup of tea or coffee sends the scent into the room.
No binding, just sew a half inch around the outside edges, no turning either.
