There seems to be a lot of brown packages created already, maybe something different to this would be best. They all seem to be quite basic too with some kind of logo or design on.
This is probably the most unique one I've come across,kind of looks like some kind of laundry basket but with slogan on it makes it appeal. I also like the fact that it can be carried as it has handles like a little bag.
The Don't Panic pack is something we recieved on freshers, more of an envelope than a box which I'm looking at making. However it works really well and something which is recognised over a range of people.
