I am learning how to make candles myself, this is my junky practice candle.
I didn't have wax paper to press it in and hide the paper while I was heating it but I'm super impressed that this was so easy and how the wax crusted over the image pretty immediately. I will try again when I have the wax paper to press it more into the candle wall.

I was also impressed that such an elaborate image would go into the wax really well.

I wish I would have spent more time on this first experiment but I am impressed enough to post.
