From the piece:

I have developed a way to use short lengths of leftovers to make beautiful knitted scarves. Once you understand the concept behind these scarves, they are quite easy to knit. … Needle size, gauge, and specific yarn amounts are not critical when you are making these scarves. I am fearless about mixing different fibers. I’m not concerned if the yarns vary a lot in size or wraps per inch either. If a particular yarn is a lot thinner than the majority, I may knit it by holding two strands together, or I may knit with strands of two different yarns held together.
