Firstly, I drew my illustration copies in pencil.
I added the first layer of water colour and some of the detail on the scarecrow. The detail on the pom-poms was done with watercolour pencils. I did this by dotting the colours to create the texture.
I started the detail on the spikes and I did the base colour for the hedgehogs tummy. I started colouring the balloons by doing a dark, slightly watery, layer of the colour and then adding a few spots of water to the lighter areas.
I finished the little drawing off by adding extra detail with a pencil to the outline and the face. Nick Butterworth (the illustrator) used a pencil to add detail as well. The tail was done by using a fine brush to make it look like it had fur.
I coloured the ear and the rest of the corks with watercolour and then I used a white watercolour pencil to make the spikes stand out. I used a normal pencil to, again, do the outline of the corks and the whiskers.
I designed my own front cover, drew it in pencil and then started watercolour. I used a light green for the base colour on the leaves and then I did shapes in a dark green to add detail.
I then coloured the balloons in the style of Nick Butterworth. I did the ladybird's body in dark grey and then added a bit of detail with black to show the body's shape. I used a pencil to do the outline so it was following the style of Nick Butterworth.
