Small Kokeshis will no more mystery for you.
There is just something I want to report, and asked me a question: the assembly, the author inserts mostly a stainless steel wire bent double in the polymer part before cooking, but nowhere I had read that after baking put a dot of glue? All those who practice polymer know that the metal (if we do not put liquid polymer before inserting it) does not adhere to the metal paste .This in part if it is not stuck will jeopardize the holding in time of creation ..... and then you will see just detach the piece and lose.
I prefer the use of micro screw, which I then glue or to the glue or to the glue Hasulith.
