Complete and utter novice here. So this is probably a really stupid question.
I'm close to finishing my first knitted thing, a scarf. So here's what happened: I finished the scarf, and realized that the tension for the first 20 rows was looser (from when I was first learning to knit) and it was more noticeable than I thought it would be.
I thought oh, I can just re-knit those rows. So I unravelled the cast-on managed to get the loops back on a needle properly (I think).
Then I realized that I can't just knit as normal because it's going to be backwards (I think?) At least, it doesn't look like it usually does at the end of the needle because I suppose it's in reverse.
So my question is, how do I add those 20 rows back onto the scarf?
