Drawing Shear Flow: Find Shear Center of Cross Section

[Osk]

I need to find the shear center of the following cross section, but to do so i need to be able to draw the shear flow. Does anyone know how you would draw it for this case and why? It seems to be pretty easy until you get a complex cross section like this.

See cross section here
