Help reading Drops pattern 130-5

Please help…I’m considering making this beautiful sweater into a washrag if I can’t get help.
Back Piece,…Then cast on new stitches in each and every row (=at the end of every row). Referring to the following: Cast on 1 st a total of 4 times, 2 st a total of 2 times, 3 st a total of one time. The beginning statement is confusing me. Thanks

Welcome to the forum!

The pattern may have been revised. It now says, “each side on every other row”. To me, the way to work this is to cast on the sts at the beginning of every row rather than at the end. It’s effectively the same thing.
Thanks for the pattern reference. It’s a really good looking top.

AT THE SAME TIME casting on 1 st for sleeve in each side. Repeat inc of 1 st in each side on every 4th row a total of 4 times. Then cast on new sts in each side on every other row (= at the end of every row) as follows: Cast on 1 st a total of 4 times, 2 sts a total of 2 times, 3 sts a total of 1 times = 168 sts.
