I've mentioned before that I often enjoy working with single repeated blocks that form more intricate patterns when lined up side-by-side. I came up with the block pattern for the lattice quilt back in 1994, as a way to experiment with color gradations and illusions of depth that I hoped to produce by overlaying a seemingly interlaced grid over a background. I don't know that the basic block is original, since the idea seems so simple that I can't imagine no one has tried it before, but at the very least, I developed it independently when I made my "Autumn Lattice" quilt nearly twenty years ago.
I always thought I would work in series with the lattice design, but it took me 17 years to return to it, when I made "Lattice II" for VMQG's Kona challenge two years ago. The current quilt is the third in the series, and I hope I'll keep working at it over the next few years.
