how do i line these up to be straight?
 

I need your help please! I hope I can explain this so that it makes sense!
I'm sewing 2 angled pieces together on the long side. Once sewed, they need to be straight across the top and the bottom. How do I line the light green piece (on the left) to the tan piece so my top & bottom edges are straight and not kitty-wompered? If I put my 'ears' together, they aren't straight when sewn so I've been ripping out a few and decided to come here for you collective wisdom.
Thanks in advance -

You just line it up and sew...just pretend its not at an angle.

you need to line up where the seam intersections are - there will be ears sticking out -
