From the Knit Picks Website:

A fun knitting pattern set to create a felted bunny stuffed animal and mini baby bunnies. Good for animal lovers, Easter toys, or gifts for children. Pattern is for an intermediate knitter; requires knitting in the round, increases, decreases, and short rows. The finished size will always vary due to gauge, yarn, and amount of felting but the bunny will be about 6 inches tall (9 inches to the top of the ear) and 4 inches wide. The mini bunnies will be 5-6 inches tall.

Recommended yarns are Andean Treasure or Bare Merino style DK yarn. Two skeins of Andean Treasure will complete one large bunny and two or three small bunnies. One skein of Bare Merino Style will make two large bunnies or one large and several small bunnies. Andean Treasure yarn will create floppier ears than other yarns.
