My First Stencil What colour is your whale going to be?" Does the elephant have big blue eyes? Stencils are a great tool for imaginative play. By simply giving an outline children can decorate and colour in their own animals bringing each one to life! These durable plastic Stencils measure 15cm x 15cm and can be easily cleaned with soap and water after being used with Paint, Markers, Chalk, Pastels etc. All sets of Stencils include both the positive and negative of the Stencil, therefore 2 of each animal shown.
