OMG - the things you could do with this! So many ways to get this effect, but I would use a plywood base and cut the design with a jig-saw. Either way, to under light this table with a puck, blacklight, or flicker bulb is a MUST!
DIY a Pallet End Table! Pallets are so versatile and so FREE! (at least here in Northern California). And THAT? Is a "very good thing" for folks like us doing a reno/restoration on our 1956 "Cottage" - on a TIGHT Shoestring Budget!
