I approach painting as a field in constant transformation, where the porosity of the fabric and the accumulation of paint produce zones of density and dispersion.

I use oil and beeswax on linen, jute, cotton canvas, and lyocell-elastane, prepared with a clear ground that preserves the color and texture of the fibers. Paint is composed of oil, turpentine, beeswax, and translucent pigments, producing deeper colors and velvety surfaces, while allowing the weave of the fabric and the layers beneath to remain visible.

The fabric is stretched and prepared directly onto the wooden stretcher, becoming an integral part of the support structure. More open meshes, such as lyocell-elastane, act as membranes that diffuse light and allow the geometry of the stretcher to become partially visible through the surface.

The orthogonal geometry of the support is tensioned by the weight of thick layers of paint in the lower regions and by the excess fabric of the stretched surface, which folds back along the sides of the painting, as if the surface were folding in on itself.
