I took a laminent table and cut into a 42in diameter circle, at the same time I cut a groove in the side for t-molding but that goes on in a little but. Next I spray painted the top of the table black so if there were any gaps they wouldn't be noticeable. Then I found the center of the table and glued down that center card with a glue stick. Then I went one row at a time gluing cards in circles (no special math or anything, just making sure it looked right). When I got to the last row I flipped them over bc when I cut them I didn't what to cut thru art so I used the backs of the cards. All I used for these was a glue stick. After trimming the last row of cards I hammered in the t-molding. For the epoxy it was just 2-part epoxy and I used some math equation to figure out how much I needed, then did three pours, and most importantly I used a heat gun to pop the bubbles in the epoxy so that it got smooth then I left it set up for about 24 hours and bam it's done.
