Crayons
Epoxy
Dremel drill
And a little bit of creativity is all you need.
I chose to curve my edges to a domes point to show off the multi layer of colours. I also used a bangle I have to measure size. I would recommend avoiding the darker colours (especially black) as no matter how much I sanded, wiped clean, sanded some more..the black seemed to stain the wood slightly.
It's a messy process, but the end result pretty neat... Next time I do plan on making from recycled crayons.
