I used a freehand tool to draw a shape that I need to fill in with color. The line is continuous and it is closed, but I didn't draw it at once. I have used a semicircle and other shapes to draw it., because for the free templates In fact I draw a puzzle piece. So, I need to fill it in. I did try to weld it, to group it or to combine, but still I can't fill it in. Someone tell me.
