Oh, you have to go to the fur layer, click on it, get the eraser and erase it! It wont erase the tail lines, just the fur. Oh and thanks, Im still trying to figure a name out!
Lol, no problem! So once youve chosen the tail you want and the fur thickness (I believe its sleek, semi-fluffy or fluffy) you have to click on the layer of the fur. Once its highlighted, click the eraser button and erase the lines inside the tail. Then when your done, you can go back to "color here" or whatever it said. Hope that clears things up!
