I'm having trouble masking drawn objects
I've been doing research on how to add a paintbrush effect to a circle but can't really get a solid answer on how to do it, a lot of it seems to making objects into compound shapes and then uniting them but it makes what I drew disappear. In short how do I add the paintbrush effects onto the black circles like the second piece. I drew the second one on Procreate and the tool was 'Alpha Lock' but on Illustrator it's clipping mask?
