Our Catherine Stained Glass Window Film. Printed onto our high quality material, make your glass surfaces come to life with our brand new Stained Glass Designs BBC's Drama 'Happy Valley' season-three finale - want Catherine Cawood's front door? We loved the tense moment as Catherine Cawood crept into her house, knowing Tommy was waiting for her inside. Being in the business of manufacturing window films and recently introducing a stained glass film range, it's no wonder we were a little distracted by the fantastic period front door. What's the obvious thing to do? Add the design to our growing range of stained glass effect window films... This is a limited edition product that we've created for fun! Want to practice installation first? All orders are sent with a FREE offcut piece of similar window film.
