I just started making bendy doll and i'm now addicted. While reading a how to wrap thread i notice that they said the glue on a bead for the head. I have very mouthy children and i didn't think that would work, so i came up with a good solution.
I bought a thingy for jewlery it looks like a tiny screw with a ring on it. I put the pipe cleaner through the ring than wrap the doll keeping the screw at the neck. when its done a screw the head on, then wrap a little more floss so it does not bobble. it works like a charm. let me know if anyone else does this and how it work for you.
