Sister is the most amazing super bulky - soft, feathered, not plied totally Un-Adorned!Ì ike Malabrigo Gruesa? and very similer to TWINKLE if you've ever used it. And none of the usually sparklies or floralies - just a beautiful, handspun bulky. Extra soft wool, no scratch factor at all (or at least, my kids scratch-tested and said thumbs up - and they are fairly critical about this fact). A perfect SISTER to any of their yarns- use sister as the main body of the piece, and add on the gypsy garden, or rolling stone, and watch yarn magic happen! Love it!
