I made these last year, following this site's directions slightly. I used scrapbook paper in Halloween themes and then bought the wooden letters, and painted them the colors I wanted. Really simple and really cute!
This is the John Boos walnut butcher block that is my island top. I ordered it here: www.butcherblockspecialist.com I was a little nervous ordering it sight unseen but they did not disappoint...it is gorgeous!!!
