Faux Cathedral Window Frame with Stone Effect

Many of our home garages, workshops and basements don’t have any windows and a popular method of faking some natural light is to make light boxes that mimic false windows that you can hang on a wall. But this won’t match the older laboratory look we’re going for.

Instead, I’m going to build a faux cathedral window frame like you see in old castles and gothic churches. We’ll start by cutting the frame out of plywood and then shape some decorative PVC trim around it with a heat gun to add more dimension. For a stone-like texture, we’ll use spackle and an old large paint brush to build up a few messy coats with dabbing motions. We also discover that it’s great for fixing any imperfections and hiding the gaps where I tried to miter 2 pieces together – and failed – with the trim at the top.
