I've had a WWI "trench art" vase for so long I can't remember when and
where I bought it.

I've always wondered how the craftsman who made it from a cannon shell
formed those smooth deep grooves in the lower part of the vase.

It's hardly unique, I've seen photos of many other pieces of trench art
with similarly formed grooves.

Thanks guys,

Jeff
