If some paste got pushed out, trim it with a scalpel. If you leave it, the body won’t sit properly on the cake dummy and it might start leaning to the side. 


Take the skewer out (also rotary motion). 


Apply a small amount of glue* on the stick where the body will go. Thread the stick through the tunnel in the body. Put the body in the cake dummy (previously created tunnel). Trim the stick to about 3 cm. 

* If you apply too much glue, it will take a long time for it to dry out.
