I love Escher and have an Escher book, but short of appliqueing a copy of an Escher design (which should be permitted for personal use), the only quilted approximations are the tesselation designs already mentioned.
If you have drafting skills, you can try to redraft the curved Eschers into straight lines and try that.

Thanks for bumping my thread BW! :D

Thanks for the links ghostrider, will have a look. BIG I know about Jinny Beyer - hers is the closest to what I was looking for that I'd found so far.

Amma thanks yes Hans is awesome and not only for that! :mrgreen:

Martina - I was thinking of drafting something myself but wanted the curves to give the sense of movement. I can't machine piece curves - well, I never tried but I thought maybe I could EPP? :shock: :D

Like I said - there's always applique. :D

Jenny Beyer is a big fan of Escher. Her book on tessellations is the best resource for fabric tessellations. She made quilts using Escher's methods.
