I got your stencil, RIGHT HERE!!!!
Look around on Ebay or somewhere for a used Marsh Stencil Machine.
I was given one several years ago, and you can crank out multi line stencils by the dozen in just a few minutes.
I use el-Cheapo black gloss spray paint.
When the stencil gets to wet after several boxes, big deal; toss it aside and grab another stencil.
The next day they are all ready for reuse once again.
If you use spray paint like I do, please make sure to do it outdoors.
I don't think the vapor is very good for you.
I strive to do my work to the best of my ability every day out of gratefullness.
