I am decorating a couple of windows at home at the moment and thought I would share a handy tip to avoid having to squash stencils into tight spaces. Apply a strip of masking tape along each edge of the pane where it meets the frame.
Stencil the pattern across the glass and over the tape. For this project I used stencil no OTT20 from the Ottoman Collection at The Stencil Library. It is a lace stencil that should work well on windows to create a privacy screen or to disguise an unfortunate view. Once the pattern is complete remove the frame of tape to reveal a slim border of undecorated glass around the window pane. This gives a neat finish and prevents having to stencil right to the edge of the panel. Our local window cleaner uses a spray of distilled water on our windows so the acrylic paint should be unharmed for a while. I put the decoration on the outside of the window because my husband cleans the inside with a chemical cleaner that I think may eat or at least discolour the parchment hued stencil paint. The next window to tackle is much higher with a boring view of a roof; this is it.
Because of the height of it I will and risk losing the decoration to cleaning fluid but I reckon by the time that the stencilled pattern wears out I will be ready for a change anyway.
