The design in the center reminds me of sacred geometry, and also a musical treble clef.

Perhaps some actual music symbols would make attractive or useful designs as well.

Sounds in nature, after all, are a peaceful and healing energetic force on people. Music has been shown capable of having a reverse effect of calming wild and domesticated animals.

Ever wonder if music can benefit trees, plants, and rocks (crystal minerals)?

Anyways, I really love the lovely tree designs on those cones. 🌲
