I would use a stencil and Plaid Glass Paint which you can get at an arts & crafts store or on Amazon. However, here's a project done by another Hometalk member who used Unicorn Spit. The glass paint will look more like stained glass. The Unicorn Spit will be a little more opaque. Wishing you the best.
Hi Bernard, the easiest way is to buy a few sticker, butterflies work really well or even a lovely quote. Stick them on the window and use frosted glass spray paint to paint the window,. Once the paint is dry remove the stickers and you're done.
This project is adorable
