Manna from heaven

Thinking about what to use to bind the dragon quilt, I remembered a bag (from a bring&buy) with some crumpled navy lawn, too fine to use among the heavier cottons, but perfect for a doubled narrow binding. Would there be enough? When I got it out to iron before cutting strips, I found it was already cut, and pieced -into 10 metres of bias binding! That saves a lot of time - thank you, unknown person who did all the preparation!
