Super Mario Curtains
You could probably accuse me of phoning this idea in, as it is merely a screenshot of curtains imposed onto an actual curtain (there’s an Inception joke in there somewhere). But what I am trying to do here is make this an actual product.
I’ve found a few Etsy people who specialize in sublimated bedding and curtains, and I believe this design would make for a good candidate. As for bedding, I’m hoping for something along the lines of the duvet cover pictured here. With matching cartridge pillow case!
This design is ideal for the shower curtain, especially if you have black and white checkered tiling present. It could also be employed for windows too.
