I love this pattern and have tried so many times to make this shwal! My question is...there are a total of 126 stitches. The 1st row is knit, 2nd row is purl, on the 3rd row of the pattern, you k2tog, 3 times, yok1, 6 times to the end. When I get to the 4th row, which is knit all stitches...I end up with 153 stitches!! It keeps getting bigger...how do I keep the same amount of stitches through out the pattern??
