3D Criss Cross shape

Hi All,

This is the shape I'm trying to achieve:



I did a trace of the 2 sections separately and am now trying to figure out how to make them in 3D. I tried 'ribs' along the length but am not sure if this is the best way forward.



Also, I'd like the pointed ends to bend down a little.

Please could someone suggest the best way forward?

Many thanks,
Gunter
