If you wish to re-spool, you need two 620 spools. It is necessary to rewind the 120 film onto a 620 spool before it can be used in the camera.
Some cameras are capable of taking either side of the spool, in which case the camera itself can be used to re-spool 120 onto 620 spools more conveniently. This accomplished by first running the film through the camera without exposing it, then, in a dark room or changing bag, holding the exposed spool in one hand and spooling it backwards onto a 620 spool using the camera as a convenient winder, tucking in the free end of the film when necessary.
You can make your own 620 spools are you can buy them online.
