Great stuff, lovely lettering Geoff.
Cant wait to see this in a piece of text form.This merits a new nib and some new ink methinks.......
Your question 1...the letter U.
Starting the second stroke with the 'leading' edge of the nib at 'x' height would give the optical illusion of being slightly shorter than the rest of the lettering.
Question 2...any special inter letter spacing needed.
The 'n' in nice, and the 'o' and the 'n' in ocean?
Will be starting some practise tomorrow morning
