The ampersand will be about as tall as a capital letter, just under the baseline of the line above. For a curved tail at the bottom of an ampersand, put the pen just above the baseline and bring it down and to the left to reach the baseline. Then, bring the pen back up and to the left to form the diagonal.
Depending on how you choose to draw this ‘C’ shape, the loop can be wide and angled toward the right, close to the first downstroke and mostly vertical, or some combination of the two.
You can go further past the diagonal for a more embellished, decorative design.
This line should be short and just visible enough to provide some definition to the end of the line. The cross of the original ‘T’ is actually the intersection between the bottom loop and the first upstroke, and not the wide serif some people draw on ampersands.
Calligraphy ampersands are typically open at the side, based on a capital ‘E,’ rather than a lowercase one, like the standard shape.
For an added calligraphic flair, you can add an open figure-eight or infinity sign by bringing the loop up on the other side of the crossed line and curving downward to make an open loop. This stroke creates the crossed ‘T’ of the ampersand.
This loop is great for designs that you want to have a care-free, fun tone.
