Stitch/ Purl alternating rows
I'm just a beginner and am knitting a scarf with alternating rows of stitch and purl. Every time I switch from a knit to purl row the first stitch always ends up very loose. I am about halfway through the scarf and one side is nice and tight and the other side has loose loops. What am I doing wrong?? And can I fix the side when I'm done or do I need to just rip it apart and start over?
