My question refers to this kind of design:
(the example is from another question here, How to cut a tiny circle in paper?)
I suppose first I will have to draw that design on paper, then I will cut it. If I draw with a pencil, pencil marks may show through the cuts.
After all I have to cut by holding the blade in my hand, I cannot expect machine level perfection soon.
What medium should I use to make an initial design on paper for paper cutting such that no marks are shown after I am done?
