I didn’t manage to find any easter egg patterns I liked that were for free. So I finally learned how to make use of svg patterns such as those available at https://www.heropatterns.com/.
Turns out it is very easy to generate a pattern and apply it to a shape such as an easter egg.
I include the svg files and a brief explanation on how I did this. I am rather inept at illustrator, to this is only intended for beginners like myself
