Confusing pattern - need help
Hi - I've hit a very confusing bit of my pattern. I have no idea how many rows I should knit now...I don't know if the 10th row is counted from the beginning of the section (where the needles were changed) or from this point on (where I got stuck).
This is the section I don't understand
"Change to 10mm (US 15) needles.
Beg with a K row, work in st st for 4 rows, ending with RS facing
for next row. (No problem with this bit...)
Next row (RS): K2, sl 1, K1, psso, K to last
4 sts, K2tog, K2. (This is ok too)
This is where I got stuck
Working all side seam decreases as set by last row, dec 1 st at each
end of 10th and foll 10th row. 35 [37: 39: 41: 43: 45] sts.
(Where does it say how many rows to knit?)
Cont straight until back meas 30 [30: 29: 32: 31: 33] cm, ending
with RS facing for next row."
Can anyone help me?
