First run at actually making complete from scratch, referencing images brushes but I saw there was no stretch mark brushes at all that I could easily find so I made my own.
The basic one is just how I would draw them by hand on my ocs and the other two are actual names of two types of stretch marks people actually have.
I do plan on making more as there are more types of stretch marks but I thought these would be a good entry point to go into.
these brushes are for ClipStudio only, as they are .sut files, but I have provided the actual images of the brushes for any that wish to make these in photoshop and share with other photoshop users so have at thee.
Did I also mention they are FREE
