Here is the link of my pattern: http://www.redheart.com/files/patterns/pdf/LW2357.pdf

Thank you for the explanation in doing the side edging. I want to know as how many single crochet do I have to make for the side edging? I did make 68 single crochet as indicated in parenthesis on the pattern but when I tried to sew the side side seams some portions doesn't have any single crochet is that normal?

For the side seams: what does the pattern mean:

Sew side seams from bottom corners toward fold line through 12 (14, 15) single crochet of both thicknesses leaving 40 (40, 45) single crochet free for each sleeve opening.

I am confused about the instruction single crochet of both thicknesses leaving 40 single crochet free for each sleeve opening.

Thank you very much for your help and patience in explaining everything to me.
