Concrete Garden Baluster Foamcut Hotwire

Draw some outlines of a baluster as seen from the front and from the side.

Cut your foam baluster mold using a hotwire

When the hotwire cube is done cutting you'll end up with a positive and a negative mold. We'll not use the positive foam baluster at this time as we want concrete.

Tape off the negative mold you just cut to prevent it from opening up due to the weight of the concrete. Once secured fill your mold with a pre-mix concrete and tap it on all sides to let air escape.

Let it sit overnight.

When the concrete is hard enough simply remove the mold and you'll have a unique concrete ornament for pennies on the dollar.
