There are a few blues at work in Lacuna.
Light blues undulate among shadowy blues, reminiscent of the shallows and drop off shelves along the Great Barrier Reef. I've got many happy memories in this beautiful part of the world.
I highly recommend gentle handwashing in cool water to prolong the life of your project. Machine washable yarn can tend to grow once washed, so please ensure you swatch, wash and check your gauge before you commence your project.
