Understanding pattern instructions for sleeves in unisex boatneck sweater for 6-9 month baby.
sleeve increase chart
I cast on 37 sts and do 6 rows in g st then increase 1 st at each end of next 3rd and every foll alt 4th row to 53 sts then on every foll 6th row until there are 57 sts. Cont straight until sleeve meas 16 cm ending with RS facing for next row. Now this is odd because I took the meaning of alt 4th row to mean every 8th row to increase 1 st at each end of row. But the measurement is far longer than 16 cms. Where am I going wrong. ..... every foll alt (4th) row to 53 sts ? Please help as I just don’t understand how every alt 4th row is surely every 8th row which means the sleeve will be far longer. Also it says ... cont straight until sleeve meas 16 cm ?
