How do you repair a crack in a wood carving?

The crack in the wood is due to the wood drying out. Go to the hardware store and buy a small tin of woodfiller. Apply the woodfiller into the crack. Depending on the width of the crack, you may have to do two or three applications. Always wait for 24 hours between applications because the woodfill will also shrink as it dries. Once the woodfill dries on the final application, and no more shrinking is visible, use a fine grade sandpaper and carefully sand the woodfill repair so that it is as smooth as the surrounding wood. Finally, go to the hardware store and buy a colour pencil that matches the colour of the wood. Apply the pencil to the repaired area. Bingo! Good as new.
