For Repousse work the corner-pieces, Nos. 29 and 31, are very easy of execution, or they may be used for flat chasing only. The modelling is slight, especially in the No. 36. The lines, having been transferred to the metal, should be firmly traced in, and, if plain chasing is chosen, the ground should be punched. In the case of surface modelling, reverse the metal, and work up the form slightly, finishing with flat raising tools on the surface. The ground may be left plain if there are no unsightly marks.
