I’ve been really struggling to find suiting roulettes for myself, and I decided to make my own. I know what I like, in the big picture, and what I’d like to avoid.
My question is: can any people who have experience in creating these roulettes give me some tips or advice?
Maybe there’s a good website for making them, maybe I should know about certain aspects like image quality or text size/color.
Any help is greatly appreciated. Thank you🙏🏼
