Two fat quarters equal a half-yard width of fabric cut.
HOWEVER - do as the others have suggested - lay out some pieces and see how it goes. The shape of the pieces makes a huge difference in what will work.
1/2 (akas 4/8) will always be more than 3/8. The problem here is if the pieces are big enough for the template.
