Oh! Okay, that makes sense! Great!
Also, I'm new to doing cables so I have another question and it's probably a stupid one...
Do I have to do this exact pattern in order to do the cables?:
"Rnds 1, 2, and 3: *P2, k1, p2, k6; rep from * to end.
Rnd 4: *P2, k1, p2, C6B; rep from * to end.
Rep rnds 1-4 until piece measures 14" [35.5 cm] from CO."
Or could I just insert "Slip next 3 sts to cable needle and hold to back of work, k3, k3 from cable needle" anywhere in the row?
I hope that makes sense...
