Ideas for Cover

I have been researching multiple patterns. Im inspired by the patterns in Indian textiles and architecture. I have been looking at a book called 'Decorative Art of India' by Susan Stronge

There's a number of really beautiful patterns in this book that I think might make for a nice a nice basis or reference for a cover. I have started experimenting in my sketchbook for possible designs, as shown below.

I am also interested in making a slip case for the book like in the Folio Society as recommended by Ben and Teresa. It woud add a really nice element to the whole design.

Below are some examples I think are really well done by the Folio Society

The Yellow Fairy Book by Andrew Lang

Mort by Terry Prachett
