Thanks everyone I knew you would come up with some good ideas, I think using them as a focus to the centre of a quilt is a nice idea, now just to find some suitable blocks to incorporate with them, pieced not applique? Something easy as I am fairly new to quilting. A block with not too many pieces.
These were my Fathers favourite colours and I think they work ok together, he was Scottish and loved the plaids and tartans, so do I!
