This is definitely one that needs a daylight photo. I’m wincing a bit at this one but it’s what I’ve got.

On the right, the redwood was growing into the fence and the roots had tunneled underneath towards our house maybe four feet away.

I had k3, *(yo ssk k1) doing the diagonal on the right with a knit 1 at the center and then (*k1 k2tog yo) doing a reverse of that diagonal on the left–which meant that when they met up at the center bottom where I did a double-decrease every other right side row three times, it was going to push the fabric upwards visually and physically a bit in that spot, pointing an arrow at the tree above. It was where the roots lifted our sidewalk. But that change of direction at the center also balanced the side edges climbing pointing upwards towards each other, and I wanted that.

With no boughs nor needles nor hawks nor squirrels nor fog the stump is just a bit bare so far. But man does it feel good to be making serious progress.
