Howto clip Geese wings

[smw18]

I have two geese and was wondering how to clip their wings an if I should clip them? They are free ranged and their shelter is the barn they have free access to.
I would like to see pictures, my grandpa did birds they had in the past but want to know about geese, how he should clip them. I have had people tell me the geese I got wont leave because their african geese, but truthfuly they came from a hatchery and they are a cross, what most people tell me.

Even if they are a african cross there is no reason to clip the wings. They are way too heavy for any true flight
