Letters that agree with each other
Two people draw their alphabets at the same pad. Both write pleasantly on paper. One font comes out looking like a page of real handwriting; the other looks like words assembled from a ransom note — every letter fine alone, the ensemble somehow wrong. The difference is never talent. It's that type is a team sport: on paper each word is written fresh and your hand keeps its own rules automatically, but a font recombines twenty-six frozen decisions in every possible order, and any letter that broke the rules gets exposed next to every teammate, forever.
Three rules carry almost all of the agreement, plus one method for the letters that break them anyway.
Rule one: the x-height is a contract
The dashed middle line on the pad — where 'a', 'o' and the round part of 'd' top out — is the single strongest signal of consistency the eye reads. Letters that honour it look related even when their shapes are wild; letters that wander above and below it argue in every word they share. Typographers obsess over this line for a reason. On the pad, glance at your finished cells in the tray as you draw: if the new letter's body is a different size than the neighbours, redraw before moving on rather than after — size drift compounds as the eye adjusts.
Rule two: pick one slant and swear to it
Upright, mild lean, dramatic italic — all read as personality. Alternating between them reads as forgery, because real hands are remarkably loyal to their slant; it's one of the features document examiners actually measure. The sneaky failure mode at the pad: people unconsciously straighten up over the session, so 'a' leans and 'w' stands at attention. Draw the alphabet in one or two sittings, and if you take a break, look at three of your earlier letters before inking the next one — your hand recalibrates in seconds when reminded.
Rule three: draw at the speed you write
The counterintuitive one. Slow, careful, watched strokes produce dead letters — stiff curves and hesitant corners that belong to no one's handwriting, including yours. The pad's smoothing exists precisely so you can stroke at natural writing speed and let it absorb the wobble. Trust it. A letter drawn in half a second with your ordinary gesture carries your hand; the same letter traced over five careful seconds carries a committee's. If a quick attempt goes wrong, don't correct it — clear and go again quickly. Second natural attempts are almost always the keeper.
The redraw-worst-three method
When the alphabet's done, don't polish everything — triage. Type a long proof sentence in the press and read it at arm's length.
1 – Squint. The letters that jump out — too big, too straight, too dark — are your worst three. There are always exactly about three.
2 – Redraw only those, at speed, glancing at their neighbours in the tray first.
3 – Proof again. If new offenders surface, that's the next round's worst three. Two rounds settles almost any alphabet; five rounds means you're now designing type, which is a wonderful disease with its own literature.
The goal, remember, is not a perfect font — perfect was never the point of handwriting. The goal is that a page of it reads as one person on one afternoon, and that the person is recognisably you. Three rules and a triage get you there before the coffee goes cold.
