Seven types of beads, 10 different brushes to play with!
I was having too much fun with the symmetry tool and ended up making a lot of beads. I was originally going for "hair beads", thus why these are so chunky. They'll look great as curtains & big chunky bracelets though. I'm a bit disappointed with how big these are, I draw smaller so I'll have to make some small beads later.

They can all change color. If you only want the lineart, use the "Convert Brightness to Opacity" function in the [Edit] menu: https://help.clip-studio.com/en-us/manual_en/390_filters/Other_Layer_Filters.htm#1364556 . The brush sizes below are 60px and 120px.




Text on the picture says "Smaller sizes look better with a layer border."
All beads except the "Saucer Beads" can be combined together without warping. Sadly, the Saucer beads warp in size due to how the beads were registered. You can always take the individual image material & add them in that way, of course. I have 3 pre-made "Mix" brushes, but feel free to remix them yourself. The material tag is "Sbeads", just search for that in the brush tips & you can re-arrange them however you'd like. :)
I also included the original bead base. They were drawn with a symmetrical ruler at 4 lines of symmetry. Feel free to create & customize your own:
