Okay, so we can't make you turn into the Master, but to be fair, that's probably just as well!
But we can offer the next best thing with this magnificent Master mask! Just download and print out the instructions and the mask itself, preferably on a colour printer after following the link on the right.
Please be very careful when cutting out the mask - you may want to get someone older to help with that bit!
Don't add the elastic to the mask or try it on until it's all cut out and ready to go. But when it's finished, wear it with pride and practice phrases like, 'I am the Master and you will obey me!' and 'Oh, my dear Doctor you have been naïve.'
Hours of fun! Enjoy and Merry Christmas!
