I am trying to fill the background of this vector white but I can’t seem to do it. I can only fill the mask shape but how do I click the background and fill that white as it I want it White with the black strokes.
i agree 1 layer 1 colour. so you would have to choose your work flow.
either you can layer each colour based on the 1st layer you have here and then build it up (ex duplicate, delete nodes, close loop, etc).
or you can do it like a jigsaw puzzle. but the jigsaw way is a bit worry some because if the notes and anchors are on grid constrain then when you resize some points will miss the mark and looks off. this will create an empty space as well.
