As of April 2016, this colouway has been updated to include some subtle variegation in the pale grey (blues and darker greys) and is now called Bright Blue.
We sell regular and XL skeins:
115 g (4 oz) is a standard skein

Our photos are intended to capture the overall feel of the colourway, but our dye lots do vary. Look here for more info about our yarn, including a description of our base yarns.
