Taking the right hand cord, make a counter-clockwise (CC) loop and lay the working end over the left cord parallel to each other.
Step 3: Step 3
Still working with the same cord, form another bight and tuck it behind the orig. left cord and through the CC loop from step 2.
Step 4: Step 4
Firm up the knot (which btw is ABoK #1133 labeled as a double noose... such a cruel irony for Valentine's Day) by pulling on each loop then taking out a bit of slack from the loose ends below. I placed a Qtr for scale. Pic should match yours so far.
Step 5: Step 5
Make another bight from the right hand cord and tuck around the back and through opposite loop on the left continuing through to the other side (going through both loops with the bight).
Step 6: Step 6
Make sure bight is through both loops.
Step 7: Step 7
Take up the slack.
Step 8: Step 8
Taking now the left cord, bight and tuck UNDER the first bight around and towards the back.....
Step 9: Step 9
..... Bringing the bight around and OVER the other cord/bight part.
Step 10: Step 10
To snug up the shape begin by pulling bottom right part (pictured at bottom of heart)
Step 11: Step 11
Phase 2 of taking up slack....
Step 12: Step 12
Turn peice over with the larger side of the heart now on the right.
Step 13: Step 13
And repeat steps 10 - 12 to tighten opposite side.
Step 14: Step 14
Step 15: Step 15
Pull both bights through like so, leaving the lines coming out horizontally.
Step 16: Step 16
Take left cord (coming from behind) and follow (above) the cord in front so both are coming out the right side.
Step 17: Step 17
Turn piece over so that both are now on the left
Step 18: Step 18
Taking the lower of the 2 cords repeat the same procedure as in steps 15 and 16. Cords should be horizontal as in pic of step 15 (only now with the double wrap inside).
