lower case o - Chancery
The lowercase "o" is a combination of two strokes as shown, below.
Rounded letter forms cross their guidelines.
4½ pen widths high. Try for a 45° pen angle. Work from a letter slant of 10° from vertical.
Space adjacent letters with opposing curves close. Space adjacent letters with parallel ascending lines the furthest apart. Don't measure! Do it all from sight and a few horizontal guidelines.
Consider spacing both sides of a lower case 'o'. The adjacent letter to the right is a lower case 'a'. To the left is a lower case 'd'. Notice in the example the two opposing curves between the 'o' and the 'a' are spaced closely. On the left, the curve opposing a line is spaced farther apart. The 'o' between the two adjacent letters appears centered though it is not.
Two curves opposing one another on a line of letters have the least amount of space between them. A curve opposing a straight line has a little more. Two letters with straight lines have the most space between them. Look for well spaced letters with your eye. Don't measure! Calligraphy is an art form which visually adjusts negative spaces.
