I just got in some maple and took a pictures of the sorted curly and quilted maple blocks. These were sprayed with Tru-Oil(tm) to show the grain a little better. Click for the large picture. Curly on the top, quilted on the bottom.
I wasn't trying to sell these here in this forum but was just trying to show the difference with lots of different blocks.
