These cement candle holders were inspired by the tetrapod structures along South Korean sea shores. Blogger HobbyDesign walks us through this DIY with step-by-step pictorials that are easy to follow. The blog even provides a downloadable file to print and use as the tracing template.
The project is not exactly the easiest, as it involves cement and complex cutting and gluing of plastic art sheets. It may take more than one day to finish depending on how fast the cement dries. It will usually need to dry over night.
Basically what you do is make a plastic mold of the tetrapod, fill it with cement and plug it with a candle to dry overnight. Afterwards, you cut off the clear plastic coating and take out the candle.
The little tetrapods are cute, simple and modern -- perfect for a modern home.
