I have been watching the wonderful stencilling videos that Julie Fei-Fan Balzer has been running this week. Hop on over to her blog to catch up on them all. They inspired me to make some more stencils.
The last lot that I made (see the post here) were hand-cut from cardboard. I liked the designs and have used them a lot. However, when I put them on the gelli-plate, because they're made of cardboard, they soak up the paint. Also, I used them with some spray paints and they've buckled a bit.
Rifling through my filing cabinet I came across some sticky-backed plastic used for covering books and a lightbulb went on. I could make some waterproof stencils!
So I took some cardboard file dividers and trimmed them to size.
Each side was then covered with sticky-backed plastic. If you use a patterned one as I have here, I suggest you stick one side, trim it, and then do the other. If you're using the clear one then it's easy to see where the edge of the cardboard is and you can just trim once.
Mark the pattern you want and cut out. I used a stanley knife (also called, I believe, a box-cutter).
If your pattern goes quite close to the edge you can add a protective border using gaffer tape (duck tape), folding it over the edge and trimming the corners. (Another Julie F-F B tip)
And there you have it - a waterproof stencil of your own design that didn't put a large dent in your budget :) I can see some time at the gelli-plate in my near future...
