I designed these for the cover cake for the book Cyril's Cake Adventure. 
 
I hand drew the scene then converted it into the stencil style which was then created by my friends at The Vanilla Valley. 
 
The two parts overlay to create both the woodland tree trunks and background and the tree canopies and tiny flowers growing beneath them
 
There are full instructions to use these stencils in a fab and easy way in my book
