This is SO beautiful, I’m test knitting it on Ravelry. It’s fun and even my husband is impressed.
I’m much further along on the project but wanted to share. The Ravelry project page is here for updated pictures.
The yarn is Swish DK in Beach Glass colorway. Needle size 6. Upcoming are hat test knits (full) and fingerless gloves and lots of other stuff to match I think, so visit my project page for a link to the designer and the test knit thread.
