Id make it even more simple and make just a one piece bow(selfbow) and only use a "soft" backing like silk,rawhide,etc....and learn how to tiller first,because more than likely your first time tillering is going to go awry. So why put a bunch of more work into a hard backed laminate only to fail....keep it simple first and learn the basics. And tillering the bow is your number one concern..not what type of material or materials you use. Trust me.
