What are these?

looks really good, I like to color combo too! Though I would pull that top in the sail panels area a bit more to get the wrinkles out (diagonal to the wrinkles towards the rear window.) wait till you have to pull a square corner dart if you want an experience in frustration.
The top arrived with some of those wrinkles in those panels. I decided to wait until we start getting some warm sunny days and drive it around with the top up. I think it will stretch a bit then and I will go over it again.
