From an issue of Jane Austen Knits, Clara's linen apron.
She did the whole thing on our two-week trip to Germany.
The bib is a lovely wheat pattern, and the bottom of the skirt is deep lace. The straps cross in back (not shown) and attach to a waistband (Clara added buttons).
I think if she were doing doing it over she'd make the bib wider, but it's still really pretty, and yes, washable.
