These wood shades look fantastic by day with the wood and the hint of the pattern showing on the inside, but when they're lit that's when they look even better.
That's when the pattern really shows through.
These are from John Lewis and are made of wood (rather than anything made to look like wood) and can be used for ceiling lights or lamps. There's two sizes available too - 25cm and 35cm. I think at £35 and £45 respectively they're pretty reasonable.
For more details see the John Lewis website.
Doesn't it look fab?
