In the 1980's, a popular mug rug idea showed up at craft sales. Made of sturdy cotton , a square was sewn and partially filled with uncooked rice. Spices or potpouris could be added. Handsewn shut, the piece would be chanel stitched ( with some difficulty) by shifting the fill. On average about 1.5" appart, but looked 1" appart due to the 3/4" thickness of rice. This mug rug ,more like an oversized coaster ,was very level and sturdy to use. Not a lot of fun to make, but mine lasted for years before getting lost in a move.
