The simplest ornament has more impact if it is raised. Keep your costs down by making your own pedestal; use a length of clay drainpipe, about a third taller than it is wide. Alternatively use some old bricks to make a pedestal. Place a paving slab on a level bed of sand; cement the pipe or place the bricks on top of it. Fix a slightly smaller slab on top with cement and finish off with your ornament; this could be a large sea shell, bird bath or whatever….
You can also use 10- and 18-inch-diameter PVC pipes cut to varying heights to serve as bases for applying a mosaic surface. Overturned terra-cotta saucers turn two of the pipes into pedestals; the third cradles a flowerpot….
Another idea is to make your own concrete pillars, stain them terracotta and put terracotta planters atop them….
Chimney pots can also make great planters or pedestals….
And why not some sawn off tree trunks or chicken wire gabions filled with stones…
