as some threads are about cutting boards and end grain c/b, here are a couple of URLs about that subject. The first is a step by step (13) tutorial about making one
I think its possible that some of our members haven't made one and this might answer some questions. The second URL is a large page of images of different designs of cutting boards that might serve as inspiration for a project for you. You can click on an image you find interesting and it will take you on further about that one. Beware though that some of the images lead to marketing.
