It seems that no mater how I pitch my tarp It has slack in the middle that form little ridges. Here's a pic of me holding the slack up-

This causes the sides to flop inwards when the wind comes and its pretty annoying. How can I get rid of this?
Also, the tarp im using is an HH Expedition Asym.
Thanks!
