This is a very simple illustration I did. I was having some trouble with the first steps of creating and image that could work as a pattern and decided to go for something simple. 

This is my original illustration 

After spliting the image and filling in the blank spaces this was my final result 

I edited in photosohop and made a pattern and this was my final result. 

I couldnt apply any colorways because when I tried to do so realized that the image had a few gaps and the color didn't just go in the background. This illustration I used helped me understand how to create the image for the pattern. It needed more definition and cleanup to work with colorways, but I like the idea of a simple pattern. 

This is the pattern  applied to a product template.
