Design Brief

Our next project at the Photographic Course is to "Undertake an image manipulation design brief", and we have a choice of three.
I think I've decided to tackle Design Brief 1 which is to produce a set of 4 themed Photographic Designs for a Charity's Stationery outlet -4 blank cards, 4 matching gift tags and 4 matching book marks.
I found out from the Internet that there is a Children's Charity called 'The tree of Hope'. Maybe I can use a few of my previous photos . My idea would be to show trees through the Seasons.
I have 3 weeks to plan all this, but I'm going to be on holiday for more than 2 of them, so I better get cracking!!
