Twinings lets the descenders and ascenders of simple Gothic develop into swashed patterns of their own. All it takes is remembering not to put on the usual serifs, and then coming back later with a small pen [about 1/20 of the letter's height, here] and carefully interlacing two lines that spring from the vertical stroke.
|The letters are given in family groups here, since those ascenders and descenders are the only ones you need to practice. |
The small lines can be done with the corner of your broad pen, especially with a marker or quill.
