The drawing and reference material downloads are supplied as a PDF file. The drawing is saved at A4 size as well as A3 split into two A4 pages so that it can be printed on a regular desktop printer and the two halves joined together to make the full size.Alternatively you can take the file to a local printer and they can print it for you at any size you like.Once printed at your required size the drawing can be traced onto your watercolour paper and you are ready to start painting!
