There has been a lot of confusion as to how this doll's bust goes together. So, here's your long awaited tutorial with lots of pics. I will link it to the poppet along, and ask Ghilie to post the link on the front page.
Three pieces: left side front, center, right side front
This shows how they will be placed before you pin them, with the corresponding curves lined up.

Pin side front to center, lining up curves for breasts, right sides together. This shows how one side will look:

View of the flip side, before sewing:

Sew from top of side piece to bottom of side piece, as shown:

It's very important to clip your curves, to make turning better.

Pin and sew other side piece, matching curves. Clip curves.

This is what the front piece will look like after turning:

Sew along back seam of back following like of freezer paper.

Cut out and turn and placing front piece to back piece, right sides together, pin, and sew. Make sure you turn the seams from the bust inwards, so that you do not catch them in the shoulder seams and create a pucker after turning.

Clip curves, turn, stuff TIGHTLY, and sew leg hole closed with hidden/ladder stitch.
This is what it should look like. Frontal view:

Now for the needle sculpting:
Take two really long strands of thread and double them. Thread needle with cut ends. You should have a loop at the other end.
Insert needle through belly button, through to top of bum, insert needle through crotch, through body, and out belly button, thread needle through loop created by thread. Pull tight. Insert needle through belly button again and work needle up to first dot on pattern and exit here. You are now going to sculpt the breasts.
Insert needle into top dot and out bottom dot. Pull tightly. Insert needle back into top dot, and out bottom dot. Pull again. Insert needle slightly below bottom dot, and out top of bum. Tie a knot, and reinsert needle, exiting at the hip. Pull tight and clip off. Here's what that looks like:

I sure hope this helps!
