Six and Seven Fibers Alfalfa yarn is a combination of SW Merino, Cashmere & Nylon. Marrying artful color and affordable luxury is what Rachel strives for in her Colorado studio for Six and Seven Fibers. Her beautiful execution of layered multicolors and tonal solids is obvious in each special skein. This cashmere blend sock yarn feels like butter. With a hint of cashmere, this yarn makes for cozy cowls, sumptuous socks and graceful shawls; four skeins will make a lightweight sweater. Many of Rachel’s nuanced colorways are part of collections inspired by Anne of Green Gables, Harry Potter, Little Women or Monet. When knitting a larger piece, we suggest alternating skeins to distribute all-over color.
