I'll use a grain filler for the back but I think that I'll skip it for the maple veneer. My big question at this stage is, Should I use black pigment to accent the maple top before going back with my white stain. I want the finished result to be a white washed center burst with black/grey stain around the edges and back.
Thanks for the tips. You've definitely helped to steer me in the right direction. Picking up a piece of quilted maple to test different options seems like the way to approach this for sure.
