I love this yarn. It's quite special, actually. I had saved up all of my miscellaneous fibers from previous spinnings and sent them off to Rachel-Marie of knittydirtygirl.etsy.com to be carded into batts. She took my fiber scraps, added some umpf and some *sparkle*, and this skein is the result!
In regards to the name, "Changeling", well... that is quite special, too. My husband told me I was a changeling when he first met me; a fairy child left in the place of a fairy-abducted human baby. Changelings are able to change their appearance (I do this constantly--with hair color, style of clothing, colored contacts... the list goes on). This skein of yarn does just that: it changes with each inch. You never know what to expect with this skein. It's full of magic :)
