I am knitting the Diamond Stitch Pullover in Vogue Knitting Very Easy Knits. I have completed the ribbing and am ready to start on the chart. The problem I am having is that I have 73 stitches as the pattern says I should have but the chart does not have enough stitches to use all the stitches. There is a 12 stitch repeat in the middle of the chart, but if I repeat it one time I only get 63 stitches and if I repeat it 3 times I get too many stitches. I am confused. I am pretty new to reading charts. Does anyone have any ideas?
