Creating a gesso resist is much like creating a fresco base. Deep layers of gesso offer the perfect base for a wash. When working with stencils and gesso, be sure to clean your stencils immediately, as any buildup will inhibit your ability to work with the stencils in the future.
Place a stencil on top of your prepared surface. With a spatula or silicone blade, spread an even layer of gesso over half of the stencil.
Pull one corner of the stencil back to ensure the gesso layer is the desired thickness.
Continue adding gesso on the remaining half of the piece.
Lift the stencil from the corner to remove it and allow the gesso to dry.
