That's what this yarn is (Handmaiden Swiss Mountain Silk Cashmere). I keep it close. It stays upstairs with me as opposed to the rest of the stash in my basement. It gets pulled out from time to time for a quick visit, a pet and a snuggle, then gets gently put away again.
I surf Ravelry at least once a week to see if there are any new patterns that are worthy enough for this yarn. Something that will use up every single one of the 187 yds of luxury this little skein has. Nothing has met my requirements, yet...
But one day, I will find something that will match with my desire for this yarn.
Until that time it will retain it's place as my most coveted skein.
What's your most coveted skein?
