As promised, a step by step tutorial on how I assemble my crcoheted baby dragons.
Step One: Gather all the body parts.

Step Two: Assembling the head. Before I stuff the head and sew it to the body, I sew the eyelids into place, and attach the eyeposts.
Here I have one eyelid sewn to the head:

And sewing the second eye to the head:

Here I have both eyelids and eyeposts in place:

Now it's time to stuff the head:

And weave the ends of the yarn through the last row of stitches:

Pull tight, and make one or two stitches to lock into place. Then weave the yarn down the back of the head to where it will attach to the neck:

Here's a side view of the head all sewn shut, with the yarn in place to sew the head to the neck of the dragon.
