I have worked a little bit on Malachite Maze lately. The center Bargello square is complete and also the next section which is called the Meandering River. The center square is mostly floss with one row of metallic and a bit of Watercolours. the Watercolours was supposed to be Waterlilies, but I wasn't paying attention! Oh well, the color is closs enough and it looks fine. There is also a bit of the yellow Neon Rays which really sets off the muted blue/greens.
The Neon Rays is used again for the Meandering River, this time in Tent stitch, then the background is stitched in Basketweave with Wildflowers, for the main part, and Watercolours for the 2 end pieces.
This design is set up so that the outer edge appears to be more opaque than the rest. This is accomplished by using heavier threads. It is an interesting concept and I'm curious to see how it develops as it is stitched.
