I'm knitting a vest in rev st st and on the back have just begun decreasing stitches for the armholes. However got a bit stuck on the next part. The pattern says:
"Last 2 rows form slip st edging and set armhole decreases.
Keeping sts correct as set, dec 1 st at each end of foll 4 alt rows."
Does this mean that I treat the previous two rows as a set? But if that is the case what does that mean for alternate rows (the last 2 rows have dec on both)? Or do I not use them as a set and only decrease on every other row:
Dec row 1
dec row 2
dec 3. . . etc
