Cosette yarn is Great!

I love working with this yarn. Such a nice feel and it drapes so well also. I started with the Petrified Forest - a beautiful dark teal and have now ordered the Miami Red which is also beautiful shade of red. Merino and cashmere…what more could you want? 😀

Cashmere… need we say more?

I chose this yarn to wear around my neck. I deserve wonderful things, and this yarn is wonderful. Soft, luscious, and in the colors I have? Bright!

I usually have several projects going at once and flit back and forth between them. This yarn made me yearn to knit just this one thing, and get it done, and enjoy wearing the resulting cowl.
