Hello, I am an advance Gimp user but I do not consider myself an expert (yet). I am interested in learning how to make cool textures and backgrounds using Gimp 2.10x. You guys can help me by linking Youtube Videos and or your (or others) instructions on how one can achieve cool background designs and textures. That way we can all learn together.

If you have a brush that you really like, you can enable wrap which allows you to make the result seamless. Created this shell texture with a shells brush I have (used a database that I paid for so won't share the brush since, well, it's commercial).

Of course I would be in remiss if I didn't play with my own textures. lol
