Inspired by the circus, Tim Burton and Halloween, I decided to knit some glitzy arm warmers. The general pattern came from here: http://ayarntale.com/2011/products/bit-o-sparkle-mitts-free-pattern/. It's very easy and great for beginners, you just have to know how to knit in the round, purl and bind-off.
For the silvery arm warmers I used Ice yarn Lame Black, Silver (I'm not sure if this product is available any longer. I had bought it a few years ago).
The striped armwarmers use Vanna's Glamour yarn in Ruby Red and Onyx. If you click on the photo you can see they both have a subtle shimmer to them. 44 stitches was too big, so I reduced them to 34 which was a bit too small, so I'm thinking 38 should be perfect.
