"Sonatina IV" is a mixed media piece featuring various action parts from an upright piano. Sticker flanges are screwed into a surface to create the center circle. These are hinged to Sticker tongues, allowing for loft and thus more dimensionality to the piece. The Sticker tongues hinge to the longer wooden parts called Stickers. In this case, the Stickers have a antique white "Sticker cloth" capping one end, while the other end has been stitched with wire to the surface. Repetitive butt flanges create the outside border.
