I created this special tree root coffee table for my clients at Sereno Canyon Estates near Rio Verde. This table was created from multiple pieces of Manzanita Burl that are sand blasted and then stitched together and leveled to form a table base for a glass top.  This piece got a 40x65" rectangular glass top.
 
I can create a similar piece for you in other shapes, sizes, wood types or different sized/shape glass top.
