Well this is very geeky and bluepeterish. I have just spent my kids' university fund on textbooks for my new course I will be carting them all over the place - eg in car for reading before nursery pick up and the kids will get their sticky mitts on them, despite my best efforts. When I was at school I used a protective film which came in a roll, to cover my books. It gave them some protection. I now want to do this again but am too embarrassed to ask my tutors/fellow students in case they think I am a nerd . Does anyone know what I mean and where I can get it? I have looked at Amazon and ask.com but nothing rings a bell.
