Here's a simple trick I use to get similar sizing when I'm making a bead set. This is my Zoozii Chunky Crystal Duo press. I made a bead that would just fit into the smaller cavity, then did my scroll work. That way my set will be beads that are matching nicely in size. Simple! I do the same with barrels but for those I use my Zoozii Kalera press. For chunky discs I use my Zoozii Nugget. You get the idea!
