What is Sueding BJD dolls

I learned a new term and technique that Ball jointed doll collectors use called Sueding. If a joint on the doll does not move properly then you can suede it. You use a hot glue gun. If you are trying to suede the neck of a doll then you pull the head up so it is away from the neck. Put a little hot glue on the head and let it harden. Then allow the head to sit back on the neck. The head will then turn and tilt the way that you want it to. Vinyl ball jointed dolls are made by hand and pulled from the molds by human hands. Sometimes they are not pulled perfectly so the joints don't fit the way they should. Using this technique really works.
