Making scrappy log cabin blocks may be something you can do. Separate your fabrics into lights and darks and sew away. Lights on one side and the darker fabrics on the other. This would mean cutting your fabrics to a certain size.
If you mean you'd like to take your scraps and just sew them together you may be thinking of 'crumbs". I hope someone on this message board can steer to you a tutorial about making them.
