First, string each of the pieces of elastic through the s-hook. This will not work if they are already tied, so don't tie them yet.
Next, you will take the ring part of the neck mechanism and string it on.
Once you've done this, string on the neck ball.
|This is what the neck mechanism will look like if you put it together right.|
Now, tie off the ends of your strings. Mine look a bit weird here because they got damaged, so I attempted to melt the ends to prevent further fraying. Didn't exactly work, so I wouldn't bother.
|You will have two loops of elastic, like this.|
Next, thread both loops of elastic through the neck and into the torso. I did it one at a time to get the knots through the neck and into the torso. Do not leave the knots in the neck.
Next, thread on the tummy and pelvic pieces. Don't cross your elastics.
Assemble the leg, starting with the upper part with the notch showing, then add the thigh.
Add the knee...
Now add the lower leg and the ankle piece. You will want help for the ankle piece and foot. It really is a tight squeeze and a PITA to do it alone. I ended up propping the doll between my legs and pulling with a combination of hands, feet, and mouth to accomplish this on my own. I'm also physically very weak, so if you're stronger you may not have this issue.
And you're done! Repeat for the other side.
