After laying out the door frame corners, I came back down to the shop to pull the clamps off my last piece. As soon as I'd removed the clamps, I realized I screwed up BIG TIME. I'd attached the 'extension' to the wrong edge of the brickmold!!! Thankfully, I was able to get the 'extension' pried off and the brickmold cleaned up. Unfortunately, I broke the 'extension' taking it off and had to re-cut a new one and I got it attached the correct side this time.

Stuff like this is why I write dimensions down and make myself notes!

I got the new 'extension' pinned into place and all that's left is some filler and I can prime this edge and then paint. Hopefully, I'll have this all installed before I knock off for the day.
