I write it with a descending curve, then go back and cross it with an ascending diagonal line when crossing t's / dotting i's/j's. Like this: https://www.youtube.com/watch?v=Cel3GtSOzow. I think that's pretty standard in English cursives.

Interesting; French standard “x” is this one. https://www.youtube.com/shorts/NCr5KgIXd2Q
