=> I'll leave the post up "as is" for now. Scroll down to see where it all went wrong. Finally I was able to start drafting my pattern, now all rulers have arrived.
I am not completely done yet (obviously) - but this is up to the positioning of the pockets.
 Today is was able to complete the drawing. So, two things that bother me a bit: 1) Compared to what the video shows, my armhole seems to be completely "off".
=> YES - It is!
2) Point 13A is way further up the back sleeve seam. One of the major things that might be responsible for these "misfits" might be my smaller head unit, I guess. Questions: 
1) The breast dart (?!) - under the lapel: What goal does it have? Is it for people with a more prominent breast? 2) Rory drew in the pocket flap for demo purposes - but I didn't see any measurements for it in the notes. Will these be mentioned later on? (I guessed at 2")
 Oh well...
 @Rory Duffy - Master Tailor , and everybody else here, of course:
Would love to read your thoughts so far!
=> Don't bother yet... I'll give yous a yell if my second attempt is up.
 Notes to self (and possibly others too): 1) This paper is sh**e. Markers will smudge, pencil is better, but leaves smudges too - Get better paper next time! 2) Decent handwriting would be handy too - so you can decipher your own numbers.
3) Get yourself a plastic grader / ruler (Imperial system) - it'll save you a lot of time. And last but not least:
4) STAY FOCUSED AND CHECK WHAT YOU ARE DOING!
(It'll save you from drawing the pattern again!)
