BTseries is an exploration of fabric’s behavior in lighting. “pina” is a table/floor lamp that has three variations (#1 – #3.) The shade uses the fabric 95% cotton and 5% spandex. The fabric is hardened to structure itself while it is configured to make specific creases for light and shadow effects as the lamp shade. Fabric is cut into square and dipped into fabric hardener, then hung in a framed structure from four corners of the fabric. This hung fabric is pulled upwards from certain points by thread with spherical weight placed in between the pulled points so the fabric will create specific creases as well as stretch itself. This crease effect follows the way how the fabric behaves itself in relationship to the pulled points and different amount of weights. The hung fabric is left to dry until it is completely hardened. The resulting creased fabric is then placed upside down to create a lamp shade with the initial four corners of the fabric functioning as legs of the shade. When the light is not turned on, the object presents itself as a certain organic object. When it’s lit from below, the lamp shade creates light and shadow effects not only within the fabric creases but also on the adjoining wall.
