Hello Brenda, What you do in Inkscape is set the stroke to red and the fill to light grey...so you don't use too much red ink...if you see what I mean, You can alter the red stroke by hovering over the number of the stroke with your Mouse and setting a higher number if you want o.k.
Bob P.S. To alter your patterns you would need to reload them into Inkscape to edit them...if you had done them in Inkscape
