I've been mucking about with this colour, Slick, that I first made in 2015. This is the second batch...
There are no light patches - any in photos is the light reflecting off the silk fibres.
The third picture is very over exposed so you can see a bit more of the underlying tones. And just for fun, there's a pic of before it got its black overcoat.
(This is a very saturated colourway. I have washed it and the rinse water is clear. If you are planning to knit this with a light colour, I would recommend knitting a small test swatch with all the colours you're using, and wash and block in the usual way. Cold water and a couple of drops of dishwashing liquid is a good bet!)
Shiny and silky, starboard is a single ply yarn, perfect for luxurious accessories. (Starboard may look a little kinky in the skein, rest assured it lies flat and smooth when knitted up!)
Fibre content: 70% superwash merino / 30% silk
Yardage: 400 metres / 438 yards
Recommended knitting needle size: 2.25 – 4.00 mm for garments and accessories
Wash carefully by hand in cool water with a few drops of clear unscented dish washing liquid (if needed). Dry flat in shade.
I try hard to take photos that accurately represent the colour of the yarn, but please note that screens all show colour a little differently. If you have questions about colours, please ask, and I will do my best to describe them for you!
