I had trouble deciding if these were dominoes, peanuts or masks, but I like the alliteration of masquerade masks, so that’s clearly what they are. I did the reinforced bottom again, with the pattern decreasing into the bottom.
The yarns are two different cashmere sock yarns. The purple is Bugga! from the Verdant Gryphon, is 70% superwash merino, 20% cashmere, and 10% nylon, and the color is called 'clown spikes orchid'. It's actually more of a sport weight than a sock weight, but it's knitting up for nice thick, warm mosaic socks. The light blue/grey is the meadow light base from Backyard Fiberworks, 80% merino, 10% nylon, and 10% cashmere, and the color is 'rainwater'. It's a standard fingering weight. Even though the two yarns are different weights, they seem to be working quite well for this balanced mosaic. I did find that I needed to purl the second pass on small grey dots, while the purple small grey dots stand out just fine even without a purl stitch.
