In the pattern it said cast on 92 stitches I'm making this for a coworkers kids and they wanted a bigger neck so I used the gauage and added 14 and some how came out with 120 stitches. For the pattern of the body my mind cannot get if in doing this correct

" Co= Even number of sts 10= 5sts odd no. of sts 5sts odd no. of sts. *Gauge: 14sts. and 20rows= 4"/10cm on US10/6mm"

The body pattern

"Round 1: K1, p1, k1, p1, k1, slm, k until next m , slm, k1, p1, k1, p1, k1, slm, k until next m , slm. Round 2: K5, slm, m1l, k until next m, m1r, slm, k5, slm, m1l, k until next m, m1r, slm." When I do that I get a lot of places markers in different spots and ones that overlap

What am I doing wrong?
