The Border Reivers

In class we have been doing a project on The Border Reivers.  We need to investigate what the  Reivers were about and to show our understanding.  We need to create 3 designs,  they can be a poster,  banner and/or T-shirt to advertise the Border Reivers.  I have done some quick drawings of some ideas I've had but now I need to collect more evidence to develop my ideas, and decide what design I am going to do.
