A rounded square edge

the begining of my red scarf has a rounded sqaure edge. is this normal?
this is what it looks like

:?? It could be that your cast on was very tight, or you’re inadvertently increasing stitches as you knit the rows. Do you have the same number that you started with?

i started out with 12 now i have 14.

Then it’s probably a combination of a tight cast on and increases.

You can cast on with larger needles to avoid pulling in and try to avoid accidental increases.
