We offer pleated door inserts (Lamborghini style!) and other items. It looks really awesome, as can be seen here!
Here's our regular pleat - parallel.
If you look at it normally the stitching is very visible...
... but pleats are 3D! Notice stitching invisible at an acute angle!
Parallel pleats can be stright or angled, as you wish.
Here's our Diamond pleat - just like a Lamborghini or Aston Martin! :)
