A Quick tutorial is to make a simple kite prop:

1. Use the Hi Res Cloth prop (the flat square) in the Props library

2. Go to the Cloth room create a new sim for it.

3. After you clothify it, click on the Use Choreographed button

4. using the Add vertices - create a 'cross' diagonally from corner to corner (to emulate the cross sticks on a kite

5. Animate the prop as if it was a kite moving in the sky

6. Simulate and you will see the results

Hopes this helps,
