Done, at last. Here is LS-12, Button Hook. It was a fairly straight forward block except I managed to reverse two of the triangle components on the base. The top diamond applique piece is really, really small. It's a little bit askew, but after all the "fun" I've had with this one, I am going to leave well enough alone.
In November Bob surprised me with a blooming cyclamen on my birthday. It soon entered a dormant period, but starting last week, blooms began to appear again.
