I'm left-handed and I write upwards. (I turn the klaf 90 degrees, so the lines are vertical)
The issue: when writing I need to support my right hand on the klaf, now if I wrote already a few lines my right hand is on the letters. Then, even if they are dry my fingers get dirty and when I move my hand I make the klaf dirty with small black dots. (you can't see from far but its not clean)
So what I did was to put piece of paper on top of the lines I wrote and put my hand on the paper.
Now, after I wrote a few lines I removed the paper, but the paper got stuck in the letters.
I don't see a piece of paper on the letter, just very light marks of paper.
Do I need to scrape every thing? Can I just pass ink over it?
ps. I'm writing a meguilah
