Look here what happens when you Shampoo Wet & Vac your Carpeted Mats on a Saturday Morning and leave to dry in the Sun.
The secret to the stripes is covered by the sensitive car forums informations act 2015 and as such must not be spoken about ever again.
When you've finished the wet Vacuuming and very little water is being lifted from the surface you need to go and get an old Credit Card (or Shell Members Card). Then and only then, and making sure none of your neighbours are watching, you take the card and using the short end you do apply pressure to the Car Mat and you do drag the card along to lift the fibres. Then you do drag the card the OTHER WAY and repeat until you have reached the other side of the mat. Stand back, light your pipe and admire your handy work.
Other stripe configurations are available on request.

By the way, these mats were the ones I bought from Carmats4U 6 years ago
