Modify a rectangle to look like this....
Hi all! I have a client who wants an effect similar to the (tiny) example below. It's hard to see, but basically I need a vertical rectangle... slanted almost like a wave. It should be rounded on the top left corner and bottom right corner... and have a slight "swoosh" effect on the top right corner and bottom left corner. I don't know what's wrong with me today, but I can't figure out how to do this. I'm sure it's simple... but it's not coming to me. Any suggestions would be greatly appreciated.
