Hello, Best you get 100 % natural beeswax in little drop forms. Warm it up in the oven at 50°C for around 10 minutes or let it lie in summertime in the sun. When the beeswax is soft, modal it to a sausage. Place it on the opening of your didgeridoo, press it well on and modulate the desired mouthpiece shape. Don't make the hole too small. If you want to do a perfect finish; you can melt additional beeswax in a tin and then dip your newly made mouthpiece once or twice inside.
