This quilt is the only one I made using charm squares. I cut them in half diagonally and used one piece right side up and the other piece wrong side up to add interest. (It is always worth remembering that fabric has two sides and you don't only have to use the side the manufacturers intended to be the 'right' side!)
The central strips to the blocks were made from a limited number of fabrics to give some unity to the design.
Our bedroom gets no sun at all during the day so I arranged the blocks to give an impression of a patch of sunlight in the room.
