This laser-cut Stencil is used to trace the shapes of the pieces that make up the Dove design. It also includes special channels to help you score the pieces accurately. Since there are so only four pieces, this is a good choice for cutting by hand. After cutting, you can erase the pencil marks if you like. There is some gluing involved in constructing the model.
This larger version of the bird from the Things on Wings Stamp Set is a good place to start if you are unfamiliar with this kind of model.
