R1(3-3-3-3-3-3) cl R and RW.
C1(3-3) RW.

Round 2
Make a clover as follows, - R1(2-4-4-2), R2(2+4-4-2), R3(2+4-4-2). DNR
Switch shuttles and make a chain C(2+4-4-4), join to the last picot of the 3rd ring in the clover.
Then, shuttle join to the middle picot of R1 of Round 1, and continue with the next part of the chain with (4-4-4-2).
Switch shuttles and repeat the clover. This time, for the first ring in the clover make (2+4-4-2) where the join is to the last picot of the previous chain.
