Macmillan Childrens Book Prize

I have decided to produce an ABC book as an entry for the prize. This will help me concentrate more on the illustrations and less on producing the text, it also gives me focus for the main 26 pages required for the entry. What theme I do not know yet. I would like to lino cut the letter shapes and use the screen printed swatches I will make to produce simple page designs in keeping with my style.
