As promised here is a tutorial for making Nesting Shapes if you find any errors please PM so I can make any amendments, but it has been tested.
To make oval or round shapes for nesting there is a tutorial here then you can use this tutorial to make the clones/copies.
In this tutorial these are some of the commands you will learn to use
- Duplicate
