This scarf is knit with alternating horizontal lace and tweed stitch panels. If you have a moderate amount of experience with lace knitting you'll likely find this an enjoyable knit.
There's enough variation to keep you from getting bored, yet the repeats of the pattern keep you from having to concentrate too intensely!
I love working with Araucania Botany Lace (Colorway: 3006, rainbow), and used most of a 100g skein for this scarf that measures 57 x 7 inches (145 x 20.25 cm) after blocking.
Most any type of yarn would be fine as long as the stitches are well defined. I'm going to try a wider version in a solid color sport-weight alpaca yarn next!
The variation is now available on my blog: http://www.thismanknits.com
