This bunny has been designed especially for Purple Stitch Project (visit the official site here, for more information). Purple is the color associated with epilepsy and that is why the bunny is purple :)
It’s really easy to make and measures 5.5" (14cm) if made with DK yarn and 3.5"(9cm) if made with fingering yarn. Yarn weight is not very important here, you can use any, the thinner the yarn, the smaller the toy will be, though.
The pattern is free but if you’re using it, please consider donating to the Purple Sticth Project.
