This is my first sweater/jumper. I have completed baçk and armholes etc but havin completed the front I have come to armholes and the pattern says to complete as per back from shape armholes until 26 less rows have been worked than on back to shape shoulders. Now the back has : shape armholes … Dec rows … (I get this bit) continue straight until armholes measure 21cm.
So how to i work front 26 rows less when I don’t have the number of rows for back just a length??
