On chart M1 of this pattern it says “Adjust to a full square” What doe this mean?:knitting: :knitting:
What are you making? What is the name of the pattern? Can you provide a link please? There are thousands of patterns so we really need more info with questions. Thanks! 
Welcome!
The pattern is telling you to work chart M.1 for ~11cm, ending on either row 6 or row 12 (adjusting the length to a full square). You may need to work a little more or less than 11cm to do this.
Thanks Jan!
That never occurred to me and I have been knitting for over 50 years.
