So I had nearly settled on the white with the blue design, when I went for another look in my fabric stash and found.... the William Morris fat quarters !
Now I cut out the foam for the seat and wrapped several of the ones I'm considering around it to get a feel for which would look best.
deep blue forest
deep blue Lodden
Paler blue Lodden
I also found this fabric
Fawn with blue flowers
Well I'm thinking the darker ones look better but still to decide. You are welcome to say which one you think looks good in then comments.
