You then need to make the barrel of the tank, I made mine 5 fingers but anything from 4/6 fingers would work. You then need two more 1 finger bubbles and then a
slightly larger 1.5/2 finger bubble. You have to make a loop around the 260 apple/tulip twist you made in the first 260, you can either hold this in place and loop it
around and back into the 3 pinch twists or measure the loop, mine was 8 fingers long.
