and the 3D nature of this seaweed on the sand
is what I'm trying to create in felt.
I had pleated the nuno prefelt below using my embellisher machine and then tried unsuccessfully to wet felt additional roving to the undersides of the pleats. So I removed the roving and just completed felting it and ended up with a bit of a ripple effect - and alot smaller piece! 
So much to learn and I'm glad I will have the workshop with felt artist Ulrieke Benner to help me out, soon.
