I'm sort of unofficially following along with Project Spectrum. It just so happens that two of my current projects fall within the color categories: blue and grey.
I don't know the name of this yarn NOR where I purchased it. I could probably scrounge around and find it in my Favorites, but you really don't want any. Originally, I bought this yarn to use to knit a bag. (What IS it with me and these bags???) I needed bulky yarn. I loved the colors so I purchased some (I don't know how much since they hanks don't really resemble hanks.). The bag never came about, so I thought this would be good use of the stash to knit a kitty bed. The pattern calls for bulky yarn. This yarn goes from bulky to almost DK or fingering weight! Thank GOODNESS this bed will be felted. I couldn't imagine knitting anything with this yarn that wouldn't be.
Yes, they are mostly black with a hint of grey. (That qualifies, right?) This is Claudia Hand Painted Yarn in Ink. I LOVE this yarn! Granted, I have not washed anything knit with this yet, so I'm hoping it holds up as well as my fav Lorna's Laces does. If it does, then it will be HIGH on my list of favorite sock yarns.
