Felicity, Large Flower, Row #2: k2, *k1, sl this st back on to LH needle, pass next 10 sts, one-by-one, over this st, yfwd, k3; rep from * to end. 26 sts
You commence the second row with 80 sts, which you will be working as one group of 2 and 6 groups of 13 i.e. 2+(6x13)=80 sts.
|Sl st back to LH needle|
|Lift 2nd st over 1st st on LH needle|
Use your RH needle to the lift the 2nd st on the the LH needle over the 1st st on the LH needle. That passes the first of the 10 sts required by the pattern.
|One st passed over another st|
|Ten sts passed over|
You now have 2 sts on the RH needle and 68 sts on the LH needle.
Bring the yarn forward (yfwd or yo) and then knit the next 3 sts from the LH needle. That (k3) includes the st you previously slipped on to the LH needle and passed 10 sts over - so, in effect, it ends up being knitted twice! (Once, before you slip it back to the LH needle, and again after you pass 10 sts over.)
You now have 6 sts on the RH needle and 65 sts on the LH needle. (The sts remaining on the LH needle, after working each "k1, sl st and pass 10 sts, yfwd, k3", will always be divisible by 13 because you are working with groups of 13 sts e.g. 65/13=5.)
|Six sts on RH and 65 sts on LH|
|Complete row 2 of pattern|
I hope that helps anyone having difficulties with this novel "sl st and pass over" technique! :)
