So, below is a clip on adding the additional scraps to the existing work AND how to push thru with your index finger to get knots thru stitches. The whole rug is 12 rounds. I have updated part 1 to reflect that they are rounds not rows, since we are obviously working in a round.
And, rope is cotton rope 1/4 inch diameter not 1/4 of an inch. Updated as well. It is available for .10c/foot at knotandrope.com (the best place for bulk unbleached cotton yarn).
