Left-handed writers do better with an upright or lightly slanted model and the paper turned clockwise so the hand stays below the line. These sheets use the vertical simplified face and no slant guides.
Left-handed writers push the pen rather than pull it, and their hand covers what they have just written. Two changes fix most of the trouble: an upright or lightly slanted model, so the hand is not forced into a hooked position to produce a right slant, and paper turned clockwise by about thirty degrees so the writing line runs up and away from the hand. The sheets here use the vertical simplified face and leave out slant guides for that reason; everything else (families, alphabet, words and sentences) matches the standard packs.
Pen and grip matter too: a pencil or a fast-drying pen prevents smudging, and a grip an inch or so back from the point lets the writer see the line. Left-handers are not slower at cursive once the model and the paper angle suit them; most of the difficulty attributed to left-handedness comes from teaching a right-handed slant with the paper straight. The sheets fit the same progression as the standard packs, so a left-hander can follow the class from the same page numbers.
