The challenge is MAGIC ... hmm ...
I had just purchased 'Texture Magic' (Superior Threads). It is a lightweight synthetic that you place on the wrong side of the fabric, sew through both layers, steam and PRESTO! The Texture Magic shrinks and takes your fabric with it. It produces something similar to 'Ruching'.
The grass and tree (leaves & trunk) are examples. It was fun and does give a 3D effect.
It looked a little sparse ... so I added a cat whose nap was interrupted by a dragonfly!
