Well as soon as I cut into it several large flaws were revealed. The previous day I had to discard a pipe because I found a flaw entering the draft hole from the shank (5 hours of wasted labor to discover that), so the appearance of these flaws flustered me quite a bit. I decided to try and make lemonade out of lemons and began shaping the pipe and chasing the flaws.
I couldn't get all of them out, so I decided to partially rusticate the area with the remaining flaw. In an attempt to frame the rustication I began to carve some lines and curves into the pipe to set aside that area for rustication. Long story short, I should have thought a bit more about how the lines were going to play into the composition rather than attack the briar like a monkey with a file.
Here are a couple photos as it stands. I'm not sure if I want to just go ahead and finish it out or try to correct those lines. Comments?
