1) When erasing a large portion, is there a point of not throwing away the small parts of klaf that I scraped away? In other words, is there kedusha on the scraped parts?If yes, please provide source.
2) I was writing a Nun, and somehow I wrote a Gimmel by mistake. Although I wasn't sure if it's ok, I quickly connected the feet of the Gimmel transforming it into a Nun - right away, a second after the Gimmel was done. Since I initially wanted to write a Nun, and right away transformed the mistaken Gimmel into a Nun - is this acceptable or I have to erase?
