His interest in exploring the framing and textiles as part of the manifestation of a painting as a physical object has emerged through projects such as Soft on Soft, where Billekvist worked with soft oil chalk on transparent netting. The permeability of the material allows the viewer to see the contours of the stenter frame like a skeleton under thin skin.

The works thus challenge the boundary between front and back and transcend the two- dimensionality of painting as a medium.
