It’s important to use your best penmanship, or handwriting. That way your audience will be able to read what your write.
You can print your words or write in cursive. Printing is sometimes called manuscript.
Manuscript is less formal than cursive and is usually easier to read at a glance. That makes manuscript good to use for filling out forms and for writing things like posters, ads, and short notes. When you write in manuscript, hold the pencil and paper this way.
