This would be a good project for someone knitting lace for the first time but not wanting to do a scarf. The lace pattern is simple and easy to remember, but just complicated enough to not be boring.

A shrug is, after all, a rather forgiving garment when it comes to fit.
Here is the cover of the book it came from--look at those nice saturated mid-century colors!
