It took over an hour, but I finally got the dried spackling (Sp?) removed from my Black Birds in Tree Stencil!
I cleaned it by gently brushing it with a medium and soft stencil brush, and then use a needle awl to clean the tiny crevices. One of the things I love about StencilGirl Stencils is their durability. I have been happily using, and abusing, this stencil for over four years now!!!
