Part 3 of the project give you the layout, the number of different fabrics (11 plus background) and the placement of the colours, to get the same effect as Ricky.
Part 2 gives you 4 of the block patterns for paper piecing, although I would suggest that each square was cut in half to paper piece and then be joined together, before sewing the squares together. It would be possible to print lots of copies of Part 2 and then renumber them according to the information in Part 3.
Part 1 looks like it is an outline to colour in for youself depending on what fabrics you have and how you want to change the original idea for yourself.
Not particulary difficult - all the basic information, excepting the fabric quantites, is there - just a bit of a nusiance that takes a bit of re-organising, counting and double checking.
