Eyelash extensions on lower lashes

[Phoenix Faces]

Hi Guys,

New to eyelash extensions and recently started up after my training. Does anyone put eyelash extensions on lower lashes if client requests them?
If so what size lashes do you use to do them?

When I trained they offered this as separate training as it was a different technique. Don't know if it took off x
