Ages ago I had what seemed like a good idea.
I finally finished the first part of the idea and am now stuck for the second part.
So the idea was to make a circle of stones/rocks and have an interchangeable centre piece.
Here is where I am so far, but am now failing to remember what the ideas I had for the centre pieces were…
As you can see, the centre bit is designed to allow you to add perfectly fitting custom bits yourself..
