Leylandii is generally considered a useless wood. The trees grow fast, the timber is very soft, and has no value as firewood or for any other purpose. In that regard, it is similar to sycamore, which is also considered a weed by many people. However, I have found that it provides excellent material for hollow forms. All those little twiglets create little knots and swirly grain, and with sharp tools and a bit of sanding a good surface can be achieved.
This hollow form was turned about a year ago and then sat on the shelve to dry out. It didn't need that long, but I could quite figure out what I wanted to do with it. So here's the end result. Under the right light, it almost looks like a night sky with clouds, where the full moon creates a soft shine.
It's just under 8" across and 4" high. Leylandii, t-shirt dyes and acrylic lacquer.
As usual, all comments welcome.
