The usual mods: Work half the increases (or decreases) on every row rather than all of them on every other row. I’m using K2tog for all decreases (hint: *knit to the marker, remove the marker, K2tog, replace marker; repeat from *; knit to the end–and do that on every row). My increases usually are “M1s”–pick up the horizontal bar between stitches from the back of the stitch, knit through the front to twist it (hint: *knit to the marker, slip the marker to the right needle, M1, repeat from *, knit to the end of the row; do that on every row). I include the increases on the first row after the center-90 section and on my bind-off row, too; working the increases on the bind-off row makes the corners pointier.
