I have a question please?

hi …

in Hazel cardigan pattern ، her

what is the meaning of these in sharp raglan armholes

[U][COLOR=“Red”]dec 1 st at each end of 4th and 0[0:0:1:0 …etc] foll 4th row، then on every foll alt row …[/COLOR][/U]

Does this mean the end of each row only, what about the opposite?

thank you …

Welcome to KH!
The instructions are to decrease at [I]each [/I]end meaning at the beginning of the row and at the end of the row (two sts dec per decrease row). Do this on the 4th row, again at each end depending on the size you’re making and then every other row.
It’s an adorable cardigan:

Thank you very much …
