There are actually plenty of projects that can make use of repurposed old windows and here are some of them, they basically don’t need an explanation, I’m sure you’ll understand how to realize them.
You may use old window frames indoors in various ways, mostly for decor and storage units. As for decor, you may use old window frames for a lot of things: memo boards, like photo frames, for artworks and creating art with them yourself.
Go for a cool space divider made of old window frames or make shower space covers of them. Storage units can be made of old window frames, too, and you can DIY various kinds of them – smaller and larger cabinets, open shelving in shabby chic and rustic style, buffets and kitchen islands with storage and so on. Unless you give a new coat of paint to your window frames, they will bring a shabby chic or vintage feel to your space.
