I like the cool feel that sheepskin gives in a car compared to leather especially if the sun has been shining through the windscreen, but I have this problem that my skin reacts very badly to synthetic materials. The first thing I do when buying a shirt is to remove the tags from off the back of the neck as that will cause a reaction. I can't sit in my wifes Bugeye without a towel over the seat as I get itchy within 10-15 minutes. My rex is ok as it is a CSE 2 so it has velour seats, not a problem. I bought a good 2nd hand pair of sheep skin covers and like most the sides, the back and around the base is synthetic and extremely itchy if any part of it touches my skin so i took to it with sharp scissors and cut all the synthetic sections off except just behind the head rest which I took in to make a tighter fit and hemed it with elastic inside so it would stay strong enough so it would still have the support at the top, I reattached all the nylon strapping and I am very happy with the result. It stays in place despite the leather being a little slippery and there is no synthetic parts to annoy my skin. It was a good opportunity to put my new 2nd hand Janome sewing machine to work. My mum was a seamstress in my grandparents pajama factory and she taught me how to sew. I have been making and altering things for over 60 years, very handy with 4 daughters with clothes that needed altering, or cutting down my sons full Sierra soft tops in to a Bimini or Bikini soft top .. LOL..
