Moira in N.E. England

I have 5 fat quarters of pretty ‘Mermaid’ fabric (all different).

I was going to cut it up into 5 inch squares to make a small charity quilt but it seems a shame to cut the fabric up.

I’m thinking of cutting 2 large squares or rectangles and one ‘thin’ rectangle from each fat quarter. They would go together to make a very basic design but would it look odd to have big blocks in a small quilt?
