Oak tree window

After a couple of very windy weeks sailing, it's back to the grindstone; literally. The sky is all cut, using three shades of the same glass and I am half way through the green. Using six different glasses in a mix of shades and textures, two are whispey semi opaque the rest clear. This really effectively mimics the confusion of colours in a tree canopy. 

As usual, apologies for the photos, they really don't do justice to the glass.
