Do you wash your stencils?
I just started venturing into the whole misting/masking technique, which I love, but I notice that despite the length of time, when I grab my used stencils to use on another project, I get ink all over my hands. This happens even after weeks have gone by since the last time I used them!
A couple of times this has caused some inky disasters on my layouts and pictures because i didn't realize I hand ink on my hands.
Oh, and I have used different types of sprays, but still get the same result.
