Sewing patterns eh?
For cuff titles, it varied between 17cm and 18cm above the sleeve-cuff's (If i remember correctly).
SS Arm eagle went roughly in-line with the bottom-edge of the tunic-pocket flap (On left arm... top pocket in-line).
WH eagle went 3/4cm above right-breast pocket, centred with button position (Again, if i remember correctly)
Rank-tabs went on the collar, leaving roughly 5cm from the edges in-case of rank-tresse.
Medal positions can be found on the web, especially from renowned militaria dealers. However you can always check in the medal section.
Hopefully this helped.
