Whenever I make mistakes (and I do), I find it easier to cut them out with snippers instead of scissors. These handy little nippers are 4.5 inches long, light weight with a color cap to protect the blades. Easy to use and carry in your project bag with no worries of jabbing your fingers because of an open blade. That's just too hardcore, man.
Comes in a variety of colors, please email me if you want a particular color.
