Using contour editor


So I created this rough drawing of a head using the brush tool. I accessed the contour editor to make my brush line match my first drawing but everytime I try to make the lines match up the width of my line changes. Now I know this is probably very simple but I am not sure what to use to make the width not change in the line of the drawing and instead have the line match the drawing before. Is there a way to access the curve handles to help reshape the drawing. Any help is appreciated.
