Thank you so much for your swift replies.
I have now finished the first sleeve and I think I am starting to understand how to read this part of the pattern which always causes me problems. I still haven't found a book that explains these sort of difficulties in patterns in detail. I guess because patterns are written differently according to the designer. I think the problem for many people is to know which number indicates how many times and which number indicates which row.
Thank you ever so much for your help. Now onto the second sleeve...
Happy New Year to everyone, may all your knitting projects turn out just the way you want them to.
