Fasten off.

To make up:
You need to stiffen the bone by inserting wire/ pipecleaners around the perimeter. I wound 2-3 pipecleaners around each other and then attached a number of these end-to -end to make it long enough to go around the entire bone. Bend it into shape, then insert in through the hole in the top. Use small stitches to attach it in place around the egdes. Bend the 'wing' sections at the edges so that then bend towards you (this will be the back of the bone).

Notice that there are 8 holes on each side of the bone, arranged in 2 columns. For the bottom 2 rows of these sew the edges of the corresponding holes on the front and back of the bone together.

 

Attach yarn to the 3rd hole from the bottom on the right side of the bone (see first image below) and sc11 around the edge of the hole. Fasten off.  Repeat for the left-hand side, then sew the cast-off edge of this round you just made to the reverse side of the bone.

Attach yarn to the 4th holes and sc9 around the edge. Sc in each of these sts for 2 more rounds. Fasten off and sew the cast-ff edge to the hole on the opposite side of the bone. Repeat for the other side

Stuff the bone firmly then rejoin yarn to where you fastened off at round 37
Round 38: Sc2tog, sc3, (sc2tog, sc) 3 times, sc3, (sc2tog, sc) twice
Round 39: Sc2tog, sc2, sc2tog 3 times, sc3, sc2tog twice
Round 40: Sc2tog, sc, sc3tog, sc2, sc2tog twice

Fasten off

Sew up the hole
