Because we carve our headstones by hand we are not restricted to templates and any set of symbols or carvings. This means that almost any symbol that you can draw can be carved on a headstone. However we need to be careful to keep the carving fairly simple and stylised if it is to look good on stone. Carvings can be in relief (sunken or raised) or sometimes a simple line drawing. For inspiration see this post on gravestone symbols.
