Stones

<--notice the griffin

Crosses, slabs, and shapes with symbols can be made by glueing foam-poster board (and possibly twine to make the lacework easier) together and painting it. Waterbased paints are a must. Textured paint can make it look like real stone. Slabs can be arranged to cover an entire tabletop if desired, such as the cake table. Something to bring the scotland theme closer.
