I know some effects are difficult to work with it often depends of what color you use and the settings fom light and brightness you use
even changing once you have the effect applied can cause
problems
here a test for waterpaper
on the green color it worked well on the yellow orange I had to play with the settings to show up
for the border effect I used the calligraphic stroke once 30 points and once 60 points to eraser
copied the first rectangle I draw and pasted it in front added the stroke and set the fill color to none and used blend mode eraser so the stroke erased part of first rectangle
