The physics of knitting. Cool stuff.
Meantime, the little miniature hydrangea that my friend Edie gave me several years ago is holding its own against the encroaching coffeeberry bush, blooming in both sun and shade. I love that what had been a small tender potted plant from a florist actually held on and thrived out there even after a stump grinder took out the olive roots right by it.
It is small but it is determined to live up to what it was meant to be.
