Crochet Chevron Cozy

I posted a teaser photo of the start of this cozy on the Facebook Page a week and a half ago and then vanished off the face of the Earth. Between Thanksgiving and the stomach flu (that the entire family had on different days) I have been offline a lot.
The crochet part of the bag is finished, I used the Moon Water Clutch pattern from Lion Brand yarn as a starting point. The pattern is free, but you will have to register with them to see it. I used Hobby Lobby’s I love this yarn and an I hook to get the perfect size to hold a notebook or organizer. I love this design, fun and easy! When I filled in the chevrons on the inside top I used black yarn only, I thought that if I made any mistakes that a solid color would help hide them.
I love how it turned out, but is still needs a lining with some stiff interfacing to give is some structure and to make it easier to slide my organizer out without snagging the yarn. That’s where you come in, I need help deciding what fabric to line it with.  I have narrowed it down to four choices: Chartreuse polka dots with fuchsia flowers, orange batik, sugar skulls on black, and that giant floral print that I have used numerous times before. What would look the best? I’m dying to hear what you think.
