Create a vector brush
I did this tutorial on a transparent canvas, for what reason I cannot remember. Use a white background for your canvas. If this tutorial helped you or you find error/need help, please notify me in the CBOX or by email at email@example.com! I know this vector isn't perfect but I was just putting down the basics to show you how it's done. Thank you!!
