Yeah and whichever way go do it, just make sure you follow your actual/real hairline.....if you frown or otherwise crease your forehead, you`ll see that the scalp skin doesn`t move whereas the forehead skin does... just trace/mark the line/curve by drawing a line using the back spine of a comb[not the teeth] ..the mark will remain visible for quite a while so you`ll be able to adjust your template to suit...... good luck.
