ABSTRACT:
A light table is used in connection with an underlying portable light source to illuminate a pattern disposed between the light table and an overlying fabric sheet. The light table includes a portable frame which spaces a translucent upper plate from a lower supporting surface over the light source. The frame also includes a downwardly facing peripheral frame channel which is utilized to clamp the overlying fabric sheet to the light table. More particularly, a plurality of resilient, one-piece hold-down clamps are placed about the periphery of the light table to firmly hold portions of the fabric sheet to the table to minimize relative movement therebetween. The clamps include a lower bracket bent into a resilient arch. The clamps snap into place about the periphery of the light table such that the arch-like lower bracket cooperates with the peripheral frame channel.
