I found a pattern for a shawl using the stitch called a Solomon''s knot or a lover''s knot. I adapted the pattern and used it to make a scarf. I used a yarn that is a ribbon yarn I picked up on sale at the local yarn store The Needle Craft Barn.
Here is the link to the original pattern and to tutorials for the stitch.
I used approximately 140 yard of the yarn (2 skeins at 74 yards each) and a size K hook
R1: ch 1 then make 25 lover''s knot stitches.
R2: make a lover''s knot in the first knot from hook. Make 2 more Lover''s knots then slip stitch to the 2nd knot from hook repeat till end.
R3: make 2 lover''s knots then connect using slip stitch to the 2nd knot from hook (this is the unconnected knot) repeat make 2 knots and connecting to the loose knots to create a mesh pattern.
Repeat until desired width (or until you run out of yarn)
Last Row: Do one lover''s knot then connect to next knot in previous row (each knot is connected to one form the previous row) Finish off
