When you get to coloring, there is a layer called "Erase HERE". Click on it and erase. Thats it You can make a design, or draw, or something. And thanks for coloring everyone!
I can't seem to get it, I pushed the erase button, but it would not do anything.
Someday everything will make sense. So for now laugh at the confusion, smile through the tears, and keep reminding yourself that everything happens for a reason.
