This is my first ever project after squares, scarves and mobile phone covers.
OK so the pattern is Sirdar Peru 8820. A tank top.
I have complete the back. I have 39 stitches on my needles. It says cast of 39 stitches. Which i can do. Then it says
" place markers markers to indicate back of neck at each side of centre"  sts.
I know how to place markers with some coloured thread but what is the 23 all about and what is each side of centre. I know it probably makes sense to the rest of the world but not me.
