In Europe we only get big leaf maple rarely but the little quilted stock I have worked with was only outmatched by koa, possibly quilted sapele and ringed gidgee. Really cool stuff.Thank you. This company used a circular sander to get the as they are. Sanding big leaf is a large subject. Walnut is much harder but easier to sand. Rough grits on big sander are ok with great caution to go very slow and for me I usually switch ot ROS. About 80 -100. It burns so easily and then you have to go back.
But once sanded, oiled and waxed, i think it has more depth and 3D than all but a few woods.
They make great booked drawer faces. And cabinet panels.
