Dojj - nothing, I'll still use it for watching TV on, and general film watching, but I just fancy a PJ for watching some films on REALLY BIG lol... The idea is the PJ screen will be put up infront of the TV, watch a film on it, and then take it down and it can live behind the sofa (I'll either make a hard board screen with folding legs so it can stand on the AV bench, or use a material screen which can be rolled up and unrolled and fitted to a removeable frame - sounds long, but on paper it's easy)
