Before you get worried, this is not that picture.

E went pine cone collecting with her Dad.  After a few lessons in swinging a hammer from Granddad, they were off, separating cones and branches, filling the bag. 

It wasn't until afterwards that she remembered the candle holder she had seen in a shop.  It was a pinecone hollowed out to hold a tea light.  E drew her picture to explain to Granddad what she was talking about.    After a little explaining, the tools were gathered by Grandad.  E lost interest once the drawing was done, leaving me with tools and a mission.

After a bit of experimenting, I can attest, you will need a vice, drill, hole saw, spade bit and a chisel.  The green pine cones were easier to shape and are probably more fire resistant.  Despite her lack of interest in power tools, E was delighted to see her picture come to life.
