Very nice job and will last for years.
Being cheap myself I found I could buy laminate flooring at HD for less than $15 at 1/4 or 1/2 thick and wide enough to have 7 inch boards after cutting off the shaped joint edges. I then covered my work surface and ran T-slots centered on the joints. Taped the material with 2 sided carpet tape and placed a few screws to keep in place. Works great the surface is smooth by putting the flooring upside down. Material is great for jigs and fixtures. I have been using it for months on my drill press table not a problem to be found.
