Abstract: A workpiece holding frame includes: a main body having a frame side; and a holding piece directly attracted by magnetic force towards the frame side. A sheet-like workpiece is sandwiched and held between the frame side and the holding piece to make the workpiece stretched taut at a lower surface of the holding frame. The workpiece is subjected to selectively both of printing and embroidery processes without having to change the resulting stretched-taut state. The holding piece has a groove for accommodating therein a permanent magnet. The frame side includes a flat portion and a rib extending perpendicularly along an inner edge thereof, and the holding piece is disposed so as to be accommodated in a space of the frame side which is formed by the flat portion and the rib. The workpiece is bent in contact with an end edge of the rib to be is stretched taut.
