I purchased a 4/4 x 7.5" x 8 ft. long board of light color bloodwood. The lumber store planned one side of the board and I planned the opp. side down to 7/8 thick. The wood piece in question was cut to 3 1/4 wide x 30" long. When I have one corner weighted down the
opposite corner is almost 1/4" off the table.
I stored the precut board in my basement standing on end for about a month in my basement. The temperature is in the 50's during the winter, and our basement is pretty dry in the winter months.
I started making art canvas frames out of exotic wood and have made 4 frames out of a much darker type of bloodwood and afrormosia wood.
I did not have to have these boards jointed and I even resawed the 8/4 bloodwood board. (wish I had a larger band saw than 14" for that)

My afrormosia was closer to the 2nd pic, but alot more wavy. I made my daughters painting 7/8" thk. x 3 3/4" wide frame.
It took most of a 8" board, and the painting was quite small.
