Then I had the top and bottom borders to do. I got one whole border strip pinned on and was about to sew when I caught myself. And good thing I did before I started sewing. I'd broken a cardinal rule of "right side to right side (unless otherwise indicated). So I unpinned the whole thing ... a copious number of pins ... and redid it ... right side to right side.
Sheeesh! A seam ripping episode averted.
