Hi JetMiniatures, It is very simple, I Print in a Laser Printer, very small, After cut the sign, and begin the play ;)
I submerge the edge of a blade in water and gently pass the blade perpendicularly tearing the surface (removing thickness from the paper) once the volume is removed with the same blade pressing on the edges I tear the paper randomly leaving it as broken. And then each signal I give random inks as I see them so they take shapes and tones of paper when drying, I do not know if I explained well.
thanks for the vote of 10;)
