I just did this one and it is in scarf style! I put it on the Danica scarf.
The instructions say to cut X number of strands of your yarn in 40 inch lengths. (the pattern says 52 but Lady Eleanor is very wide. I used 14 on each end of my scarf I believe. It has to be an even number.)
Then you take one strand and loop it through the end of your scarf just like you were adding fringe normally. Fold in half, pull it through with a crochet hook, and then pull the ends through (ya know?) Do that all the way across the end of your scarf.
One inch below the end of your scarf you will start knotting. Skipping the first strand of your fringe knot the second strand of that fringe to one strand of the second fringe. Do that all the way across. there should be one left when you get to the end.
The next row, about an inche below the knots take the first strand that you didn't knot in the last row and knot it back together with it's original partner. Go all the way across and knot the partners together.
Repeat for as long as you want and then trim the ends of the remaining fringe so they are all even. I did four rows total on my scarf. I gotta tell you the people who have seen the scarf are just enamored with that fringe!
