For very quick and easy grass covered graves with a rounded headstone I used a rectangle of tiling as the base (anything firm will do such as balsa).
Cut the end off of a lollipop stick to give a rounded headstone. Covered the base with filler in a shallow mound shape and stuck the headstone in at the same time.
Paint the ground brown, the headstone dark grey (highlight with light grey leaving a cross in the dark colour) Finally flock the ground.
Actual cost adn time was very small. To make the lollipop sticks go further I used the other round end and then cut some rectangular gravestones from the rest of the stick.
Does not give you very gothic graves with crosses and ornate bases but is very quick adn easy (was for last years blam and had a lot to do in avery short time)
Have fun creating
