What size are your blocks? What look are you trying to achieve? It you just want a scrappy look without one color blocks why not try half square triangles. They are easy but can be organized in many different way ie. color waves,by the way color charts are arranged going through the color spectrim, etc. into pinwheels, into star blocks....If you don't want to match corners you can put stripping between the rolls and strips. Smaller size strips are better for setting blocks Hope this gives you some choices if you want to change the look
