Being modeled by my dog:
It was surprisingly easy to do the stripe, I was expecting everything to fall apart! The real challenge was keeping the end from unraveling when I was done, but I managed... barely.
Welcome to knitting, the hobby where you too can find out how difficult counting can be.
Two things I noticed:
- The scarf curls inward, likely due to you using stockinette stitch. Meaning all knit stitches throughout, when viewed from the "front." You can prevent this by alternating knits and purls column-wise. Keep in mind that a knit stitch on the "right" side will be a purl on the other. Hence the name purl-side.
- If I'm not mistaken all your stitches are twisted. This happens when knitting a stitch through the back of the loop and results in the yarn crossing over itself rather than looping. Unless this is intentional, of course.
