I have a problem understanding a knitting chart.
This is the link for my project: http://www.yarnspirations.com/patterns/fair-isle-yoke-pullover.html
There are k2tog sts in the chart, e.g. the k2tog on the 3rd row. Do I do the k2tog once at the end of the round or I do it every thirteen sts? The same on the 6th row. I only do the k2tog once at the beg of the round or not? The same on the 11th row,23rd, 25th and so on.
I would appreciate any help
