Hi! I am just learning to knit, thanks to this wonderful website! I have mastered casting on, but I have a question about the knit stitch. When I reach the end of the first row of knitting, the last stitch I have is always very big, loose, and will not tighten. I know I am doing something wrong, but I am not sure what it is. I have watched the video demonstrating a project from casting on to binding off, but I can’t pinpoint where I am going awry! Can anyone tell me what might be the reason for this and how I can fix it?
