The size your overall nautical rug will be determined by the finished size of your ocean plait knot. To set the rug size, still using the short end of the cord or rope from the previous step, form a second loop in the cord leading off from the bottom of the first loop over to the bottom right side.
The length from the end of this loop to the top of the first loop will determine the size of your rug. If you are working in 1:12 scale, this distance should be 3 to 3.5 inches. (7 – 8 cm.) For a full size rug made from climbing or other rope, it should be 3 to 3.5 feet. (1m to 1.15m)
