You might have noticed on your search that there are a number of round options out there on the market. Round options serve no additional purpose over the more traditional rectangular designs, but they are something that is gaining in popularity. They typically come in very intricate designs that mimic the designs found on ornate rugs and therefore look unique when placed on the sand. There is no practical reason to buy a rounds design because they don’t don’t anything better than the traditional styles. The one reason one would purchase a round design is that they like the way that they look.
