This blank is called Fractured Fuchsia from Bear Tooth Woods. It's more than translucent, it's actually see-through in places. So I sanded the inside with my patented sandpaper-on-a-stick, then painted and colored the epoxy. I wasn't taking any chances. It ended up very pretty after polishing, but can anyone tell me what the "wrinkles" are? I've seen them before in blanks, but have no idea what causes them.
