Brushu: Brush strokes

Drawing Strokes: The three simple rules of drawing a stroke are indicated below

HORIZONTAL strokes are written from LEFT to RIGHT and are PARALLEL. VERTICAL strokes are written from TOP to BOTTOM. HOOK strokes run from TOP LEFT to BOTTOM LEFT or RIGHT.

Stroke Order: Proper stroke order will be essential to your ability to properly proportion your Kanji writing, and to render the cursive or semi-cursive handwritten calligraphy style. The guidelines, as issued by the Japanese Ministry of Education in 1958, are summarized below. The rules are given in order of importance:
Drawing of characters generally proceeds from TOP to BOTTOM.
Drawing of characters generally proceeds from LEFT to RIGHT.

Additionally: When strokes cross each other, HORIZONTAL strokes usually precede VERTICAL strokes. In some circumstances the VERTICAL stroke does precede the HORIZONTAL stroke. CENTER strokes are written first and then the LEFT and RIGHT strokes if the LEFT and RIGHT strokes do not exceed two strokes each. OUTSIDE frames first, but BOTTOM closure is last. VERTICAL strokes drawn through the CENTER are written last. RIGHT to LEFT DIAGONAL strokes precede LEFT to RIGHT. Strokes which cut THROUGH the middle of a Kanji are written LAST.
And: Kanji should be of UNIFORM SIZE, as they are in this "Kanji Practice Paper" sample:
