Blueberry Season in the pacific northwest always means it is time to make boxes. Over the years I've made several hundred of them and they are one of my favorite 'Zen' projects, + or - 1/4 inch is just fine as the dimensions are not important as long as the berries don't fall out. Glued and stapled makes them rugged enough to handle the tasks and the berry customers are happy to get the wood boxes. The wood is usually Douglas Fir from trees that have fallen down in the area, but i've also used cedar, cottonwood, oak, and wild cherry. We are fortunate to have a small sawmill to cut the lumber into dimension size
