Tartan for porsche car seats We do love the random nature of our work and today we have been helping a customer choose which tartan fabric to use to re-cover the seats of his Porsche! This is not the first time we have supplied tartan fabric to upholster car seats and the Porsche is certainly the most common request, but we have also supplied fabric for Mini Cooper, VW camper van interior deco and long distance lorry driver's curtains. We recommend the polyviscose tartan fabric as it is hard wearing and washable. Just in case your Porsche needs a makeover!
