The set includes 4 different shades of glass paints. Can be used to decorate glass, mirrors, bottles etc. The paints are quick drying, flow easily and produce a beautiful result. How to use: Design or print out a shape you like, take the transparent base sheet and draw a black outline around the edges of the shape, then paint inside the outline with the colours you want. Once dry, remove the shape from the base sheet and stick it to a window or other smooth surface. Can also be painted directly onto glass.
