Hello...here is what the pattern says
Sleeves....Cast on 27 sts. Work in Twisted Garter St for 6 rows. Work in St st. inc 1 st each end every 4 rows 8 times, every 6 rows 5 times...53 sts. Work even until sleeve measures 20" from beg or desired length.
does this mean I knit 4 rows then increase on the 5th or do the increase on the 4th row?
Thank you in advance for your help.
