I actually did have a list of the steps to take, and yet not written so clearly that my 'today' brain could figure them out. It was though the image that I had of myself when I wrote the note had become outdated. It was a trap to think I would always think the same way one day as I would in the future. Its not that I want to dummy-down my notes-to-self, however I do need to make them more clear for anyone to read.
I will re-write them, not really changing the notes as much as clarifying my own instructions. Clearly, what I had was outdated. There are cuts on each side of the block. Each cut is specific to make the block 12" unfinished. It is a modified rail fence block. Scrappy.
