Yup, can be done with scissors :) But hey, why don't you just go to Kroger and get some regular clippers for like 15 bucks? It's what we did ... and we clip nose, bridle path, coronet bands... they don't last as long, and you have to be careful, but it's cheap :p
I just use scissors. I'm only trail riding and only make mine wide enough for the bridle to just set down in. So I grab the chunk I want and cut as close to the root as possible. Looks fine and its quick and easy. Now if you were doing it for a show or wanted a longer section - it might not work so well.
