I have made a number of her boxes but have run into an issue I do not understand. For the Boa and Cobra boxes she states "you will need to back out of the round drawer cuts". This is on page 34 of her book. For the life of me I can not figure out what she means. I do not see a cut I need to back out of. I am using the last of my old growth pine to make the box. I can afford to make a mistake. Has anyone made one of these boxes and would be willing to explain what I am missing?
