I have tried this simple heart pattern over and over again but the rows 11-15 aren’t coming out properly. I’m quite new to knitting but I think I’m following it correctly, purling the grey stitches on the right side and knitting them on the wrong. All the other stitches are coming out correctly but these 5 in a vertical line are totally wrong. Loads of people have said the same in the comments on the pattern but no-one seems to have the answer. Your help would be greatly appreciated.
