CH6 Techniques to Try! Using Sandpaper:
Fine grit sandpaper is to smooth baked clay edges, and it can be sanded wet or dry. The colors look better sanded and they can look more professional. If you use the wrong grit of sandpaper, it can scratch grooves in the piece. Automotive sandpaper made by 3M works great because it can be used wet or dry. It needs a super fine grit of sandpaper to work on polymer clay. Start with 400 or 600 grit sandpaper, (the numbers get bigger as the grains get finer). The finer sandpaper you use, the smoother the piece becomes.
Wet sanding:
Fold your sandpaper and put it in cold water. You can add dish soap to help sand your piece.
