Thanks, Mickey.

I've watched a hundred videos. Read a hundred explanations. How people get it crease free is beyond me. They must be using some special type of cling film or sellotape. I'm told the outer isn't as important, so it's gonna have creases in it. Otherwise I'll still be here this time next year trying it. I saw a template photo on one of the other main suppliers, and that had a bunch of sellotape imperfections in it. As usual, nobody seems to have the definitive answer.
