I recently did a step-by-step DIY for the MAKE section on The Thousands. The Thousands are kind of alt city guides for all the capital cities around Australia, and Danielle from Six Thousand in Perth asked me to do this concrete DIY for them to feature.
If you’re interested in making your own concrete incense burner cone, you can see the whole MAKE here. Or if you’d rather just buy the finished product, I sell them over at Tasi Masi 🙂
