Hi!

I'd avoid using bubble wrap if I were you, or any other plastic wrapping. Papier mache needs to be able to "breathe". I'd recommend some tissue lightly wrapped round then maybe a towel or blanket draped loosely round it. Six months is a long time however. It would be better not to wrap it up at all really. It also needs to be kept at roughly the same humidity. See "Conservation of papier mache" article: http://www.papiermache.co.uk/exec/cms-d … iew/id-30/

Hope this helps.
