This pattern was inspired by the image Julia0bb by Adam majewski. It is a combination of a Fatou set and a Julia set and was calculated with a computer program.

The pattern consists only of the front side, which is worked in Double Knitting. In order to turn this into a pillowcase work a plain back side and attach them. You can also sew the finished knitted section on a material pillowcase.
