Some sort of crease in the klaf?
I Baruch Hashem am about to finish another Megillah Esther, and as I am writing I noticed a crease or fold in the middle of the amud I am writing on.
How would you fix this crease? Use sandpaper and sand it down?
Or would you keep it there and write over it? (Although I'm more afraid of any letters cracking due to it)
