Mending and Blocking An Estonian Shawl

About four years ago I made the Queen Silvia shawl from Nancy Bush's book Knitted Lace of Estonia.  I loved working on it, and it turned out beautifully, but I hadn't washed it since then.  I recently soaked it in some woolwash (by hand, in my tub) and then re-blocked it.

 
During the blocking process, I discovered a hole.  Because it was in garter stitch, the hole looked bigger than it actually was.  Only one row had unravelled so far, across three stitches.  I started by picking up all the loose stitches on stitch markers.
