ABSTRACT:
A device for marking opposite sides of a double-layer of materials for clothing or the like having a pair of tongs with an upper arm positioned between a transparent or translucent pattern and the upper layer of the material, and a lower arm positioned between the lower layer of the material and a work surface. A handle end of the tongs positions the opposing open ends of the tongs under the portion of the pattern being transposed onto the material. The top of the opposing open end of the upper arm of the tongs has an outer dot or point sharply contrasting with the surface of the outer end, and an inner marking substance or chalk secured precisely under the contrasting dot. The opposing open end of the lower arm also has an inner marking substance or chalk, and the upper and lower inner marking chalks oppose each other so that when the arms of the tongs are pressed together they meet on the opposing sides of the upper and lower layers of material to mark opposing points corresponding to a point on the pattern.
