How to identify the different figure configurations in wood

I have recently realized that not everybody can tell the difference between the different configurations of figure patterns in our pieces of wood. so I thought I would give a quick tutorial on how to tell figured quilt, flame, angel step, exotic, stained and spalted figure patterns 

Quilt - The quilted pattern is the bubbly that almost looks 3D like its popping out of the wood 

Flame - The flame pattern is pretty self explanatory it has the same sort of 3D effect but with straight lines that resemble flames

Angle step - The angle step pattern is probably most unique streamline figure pattern I can think, it is typically formed from where a branch grows into the tree and forms a v when we split the top into to pieces 

Exotic - The exotic pattern is simply every figure pattern that just doesn't fit any of the categories and it is just a odd ball pattern

With all those figure patterns there are more characteristics that fall under those categories like something being stained and or spalted

Stained - The red or purple stain you can find in some of our tops comes from a tree being on the ground getting wet for too long in the sun and sometimes it looks cooler than the normal white top would have 

Spalted - The spalted pattern is the light soft wood that has black lines through it in unique patterns every time, sometimes it has clean spots that shine through and it creates what looks like tear marks in the wood, spalted is essentially the last part of the cycle before the tree would rot
