An easy way to create a planked look on wood is to score it with a ruler and butter knife. Then pencil in the scored crevice. To get even lines, use a graphic software and space out the lines half inch apart. Lay circle in template and line the ruler up with the lines. Easy peasy. Also, I had to cut a 5.5" diam. Circle for the door. Then keep sanding it down until the rotten thing fit!
I'm a maker and a thinker. I live in a magical world inside my head. To some, I am an artist. I am surely creative. And my creations change as quickly as my mood - so you never know what you're going to get.
