Start with the usual slip knot, then chain one (the first A loop). Insert the hook into the slip knot loop again and draw up a second loop (first B) onto the hook. *Draw a loop through both loops on the hook, forming a new A. Then insert hook through old B and draw up a new B on the hook* Repeat between * to the desired length. For a flat piece, draw the A and then chain as needed for the first row. For a closed circle, slip stitch A to the edging and then top loop to top loop, the proceed as required.
