This image sort of reminded me of both a flower and a sunrise or sunset. I have the image in dark teals and rosy tones in my doodle section, but really liked this color combination better. Found it more striking. Easy swap if they prefer the dark teal, or any other color combination.

Attempting to stay very clean and simple with this one.

Envelope: Rear return address is probably frowned upon by the USPS, but common practice and often more attractive....and hey, their service is already lousy, so I don't much care as long as they don't charge the client extra.]

Will be a single side printing because it's on the flap.
