My candle melted in this very interesting way looked almost like lace! I did a bunch of failed attempts to do this, making the lace wax was harder than expected, but I love a challenge so I did not give up...

Still not 100% satisfied with the end result, but I will definitely give it a go again sometime in the future, with fresh eyes.
Failed attempts (that I definitely learned a bunch from!):
