She is spinning the Humbug and plying it with 70/30 Alpaca/Merino. I think it will look fab, especially as she has been able to really separate the colours when spinning. This way you really get the effect of the natural white, next to Oatmeal and Brown. I can't wait to see what she knits up and will follow her progress on her blog at http://puddytatpurr.blogspot.com/
Sam is also on Ravelry under Puddytatpurr, so do pop by and say 'Hi' to her.
If you would like to try some humbug for your self, then check out my website.
