I purchased polymer clay for $1.79 and liquid adobe clay for 90 cents. I then formed the clay, baked it for 20 min at 250 degrees, let it dry, painted it, sealed it and added hooks. These quarter size pearls were created specifically to match the three paintings I called Three Oceans which are shown in the above photograph. The paintings and the medallions have an earthy feel which is exactly what I was going for.
