I know what I want to do, Im going to make three sail designs for each of my ships, but I have no idea how to make it considering I don't have Photoshop and I've tried Drawing it but it looks no good, so I was wondering if anyone had any recommendations for what program/website to use? Here's an idea of what I want to do for the main sail of my main ship.
Riptide Conqueror - A Skull with a pirate's hat on it with a Trident and a Cutlass crossed below it, with two cannons blasting away from the skull.
I have similar ideas for the Voyager and Explorer just need a hand doing this
