what about a plain white cardboard box with a small label plain enough to look nice - if you didn't like it plain you could colour it in!
because this project will collect a lot of VERY different pieces from very different people with very different sensibilities, perhaps the container should just be that - a container - something to keep the pieces in, an integral part of the whole, yet not a distraction or an additional piece.? i think that no matter what we come up with there may be problems - it's a random project - so many different things will turn up that no one type of container may suit all a lucky dip bag? (groan!) although if there were a couple of chupa chups and a bajooka joe in it i'd be happy to get one! a
