Cross-stitch is definitely on the list of boring hobbies only old people like—right up there with stamp collecting and bird watching. But after years of politely blowing off Grandma’s offers to teach you, you’re going to wish you had taken her up on it. Artist and designer Theo Humphries takes typical cross-stitch patterns you’d expect to see on your grandparents’ sofa pillows and jazzes them up with unexpected details. With a few small changes to the pattern an adorable polar bear becomes a merciless baby seal killer and a serene countryside scene becomes the site of a nuclear explosion. If you’re interested in making your own Crapestry, Humphries explains the process on his website. And if that sounds way too hard, all of the artwork featured on the site is available to order.
