Crafts - My love-hate pixie coat

I've learned to knit, sew and crochet when I was in the single-digit area age-wise and I've been working on things on and off for some time. The big passion for those things came when I was pregnant and started making things for my kids. If you have an account over at Ravelry you can check out my my profile and a few things I have made over time.
So... there are some knitting communities over on Facebook, too, and seeing what was a relatively simple description for something along the lines of a Pixie Coat I decided to make one for myself. Being a half-goth with the favorite colors of black, dark gray and purple (blog colors, anyone?) I went to hunt for the appropriate yarns. I ended up at one of my favorite yarn stores, Wedermann, with the helpful ladies there suggesting I use fiber normally used for knitting machines, two strands of each color:

 

So far so good, I love the color combination and after some mistakes on the way which made me unravel a third of my work and not look at the coat for a few weeks out of frustration it's nearing its completion! I need to decide on which kind of fastening/closing mechanism to use - zip? Buttons? Some kind of clasps? We'll see - I'll keep you posted and will put up pics of the finished thing as soon as I can.
