These "Scrappy" bunnies are created using left-over odds and ends of commercially spun sock yarn - no two bunnies are alike. See photos and variations to see which bunnies are available at any given time. The bunny is knitted using an antique sock knitting machine and then is shaped by hand with careful stitching. Since these are created with left-over bits of sock yarn, exact fiber content of the shell may vary (different kinds of yarn), but usually somewhere around 70% Superwash wool and 30% nylon. Stuffed with Polyester Fiberfill. They are machine washable, but as with any stuffed toy, machine washing may rearrange the stuffing inside. If you need to wash the toy and need the thoroughness/ease of a washing machine, place in a garment bag to wash and allow to air-dry (dryer use not recommended).
