"He who marches out of step hears another drum." ~ Ken Kesey
I personally don't believe in a one stroke white on cotton and blends, maybe on some polys, but where there are fibers, there is a need to print flash print for 100% opacity (or just use discharge when possible ).
No fill stroke here, I hate them. Only flood strokes. Fill strokes break down emulsion and wears out mesh. Just my 2 cents.
