The frame of the table is built out of 2x4s and the top is three small hollow-core doors we got from the Habitat for Humanity ReStore for way cheap. They're great for the table top. So far I've also been enjoying using the table for other projects too (as long as I don't get crafty stuff on the cutting mats).
Thanks to Dad and Mike! The cutting table was the icing on the cake for my yummy work space!
