Knitted Scarf Pattern for Handspun Yarn

Sometimes I see a pattern and it just sings "knit me"!  I saw this one on Pinterest this morning and lucky me, the pattern is free on Ravelry.  

And here is  a link the the "Simple Arches Scarf" by @Megan Ellinger:

The author used handspun and it will be fun to plan the handspun I'll use to knit this scarf. Wonder whether I could double the width for a shawl? I'm thinking that an alpaca/ silk/ wool blend might give just the right amount of drape. 

Enjoy!
