As the stall will be based in Ravensbourne, artistic material like pencil cases, rulers etc will be more likely to sell as they are useful within college. Plain pencil cases can be bought online from around 1-2 pounds each (for example at http://www.cc-craft.co.uk/pencil-case-1-pc-light-natural.aspx) and could be sold for around £3-5 after being customised. Alternatively, pencil pots can be made using card by hand:
We could also sell sketchbooks or notebooks by buying paper in bulk and binding them with our design on the cover. We can also print our own art books in the University.
