Joining two butcherblocks in length

Pretty self explanatory, wondering if anyone here has done this or has any ideas/tips. I need a 12ft stretch of butcher block for my kitchen counter. Longest one I can find is 8ft.. I assume just join them with hardware and glue, sand and should be ok? Trying to make the seam as invisible as possible. Authentik 25" W x 96" L x 1.5" T Birch Unfinished Butcherblock at Menards®
