She sat on the floor in front of the television and crossed her legs.

She sat down across from him and crossed her long legs.

I made a face at him and crossed my legs.

Sitting in a bar trying to remember not to cross her legs like a girl.

He knew what she wanted and sat on the floor, crossing his legs.

She caught him looking, sat up and crossed her legs.

Finally, he sat down in the single chair and crossed his legs.

Crossing his long legs, he looked up at the sky.

At a table with hardly enough room under it to cross your legs.
