The design team, who work closely with Tate Modern in London, provide 24 postcards with six different designs to choose from. You can experiment with the colour combinations, using crayons, pencils, felt/fibre tip pens, and even paint on these uncoated postcards. A brief introduction gives some tips on using colours and suggests colour combinations to use on the specific designs, but you are encouraged to let your own creativity get to work! Great fun for all those looking for a burst of creative expression and useful for designers of all types who want to experiment with colour. The cards can be kept together in the book or detached, framed or posted to a friend.
