I do the same but...it gets really annoying xD; I prefer getting it in one shot~ And yeah, I know scanners do that. My original one cut off more than others though :\ Sometimes I use like pencil lead casings xD; I don't need it to go all the way down the side, just a little bit. I've eyeballed it before but...again. Kinna hard. And having to do multi-scans where you have to scan a large image in several parts is even more annoying when a part comes out slanted ;_;'' ..And I get OCD >_>;;

You realize I like to pile things on myself, yes? xD; But I seriously wouldn't mind helping if you ever came into a pinch.
