Materials:
Scrap yarn--only takes a few yards of 4 ply
Size G hook
1-10 mm wiggly eye
1 tiny black pompom for nose, and a bigger white one for the tail
1" pin or piece of magnet strip for the back
(Bunny is 2 1/2" tall to top of ear using 4 ply worsted weight.  2" tall using sport weight)

Directions:
1) Ch 4, sl st to join and form a ring
2) Ch 3, 14 dc in the ring, sl st in top of ch 3.
3) Ch 2, (3 dc, sl st) in next st.  (Ch 7, sl st, ch 7, sl st) in next st.
4) Fasten off.
Glue or sew on the eye, then glue on a pom-pom for the nose, and a little one for the tail.  I used a small piece of cotton ball for these bunnies. I use dental floss to attach sew on eyes for added strength.
SAFETY NOTE: If you want to put these on baby hats, I recommend stitching on an eye and tail using yarn so they are safe, and then washable too.
