I have a silhoutte cameo and use it to stencil to paint wood but have been asked recently to help a lady renew some old windows and paint designs on them. I just used the normal stencil I do for my wood but the paint peeled right off with the stencil. What stencil is best to allow me to have the same outcome on a window as I do my wood? I prefer crisp clean lines and also what paint is best to use??
