How to make/where to buy?

Hello, I am completely new to all of this and am hoping someone could help. I want to make bubblegum beads with with polka dots, gems and ones that re faceted. I do not see any molds out there for these with the exception of the faceted, but its smaller and European style or a sphere. Is there a mold or is this a makeshift kind of thing? I’m trying to use larger sized beads for childrens necklaces. TY!
