I love gifting in boxes (and recieving them!) because they're great for re-using and also for storing special / fragile Christmas ornaments.
They're also great if you like to fancywrap but you also like to do it well ahead of time, giving plenty of opportunity for bows to dislodge/be squashed/be undone by toddlers etc. Just do your fancy gifty, then pop it in a Christmas box! Two gifts at once. Course it helps if you gift to people who give the box back if they would otherwise throw it away.
There's lots of sites to tell you how to tizzy them up too.
