In this class I will show you how to create a seamless, repeating pattern in Procreate. I’ll take you through drawing out a rough sketch, inking it, adding colour, and finally how to make your pattern repeat.

Once you’ve watched this class you should be able to use the techniques shown to create your own repeat pattern.

I’m using procreate in this video, but if you prefer to use other software such as Photoshop you should be able to follow along too.
