Practitioners of Copperplate and Engrosser's Script know that the spacing in these scripts is fairly 'automatic' i.e. things fall in place rather nicely when the exit hairlines are drawn correctly and meet the following letter at about halfway up the x-height. It is interesting to ponder exactly why that is so.
It turns out (no pun intended) that the bottom turns of the straight letters (i, t, l) etc are actually similar to the rounded letters (o, c, e). When drawn correctly, i.e. like the bottom right side of an 'o', exit strokes will be at the correct angle (i.e. match the slant) when they meet the following letter. What is even better is that the join won't be jarring even if the hairline meets the following letter a little bit below the halfway point - this typically results in an abrupt 'impalement' of the hairline into the following letter if the hairline is drawn a bit too shallow.
Here is an exercise I give the students. The following image shows the bottom halves of 3 words 'ice', 'lit' and 'tie' - can you tell which one is which?
(you can see the full image here)The challenge is to write these three words and show only the bottom halves to see if the words are recognizable. I will be looking forward to your participation.
