So I tried again this evening. This one turned out better but still not perfect.
Knit one row
You will make eight wedges. Here's the pattern for each wedge:
Row 1: knit to last stitch (leave last stitch unworked), turn.
Row 2 and all even rows: knit.
Row 3: knit to last 2 stitches, turn.
Row 5: knit to last 3 stitches, turn.
Row 7: knit to last 4 stitches, turn.
Row 9: knit to last 5 stitches, turn.
Row 11: knit to last 6 stitches, turn.
Row 13: knit to last 7 stitches, turn.
Row 15: knit to last 8 stitches, turn.
Row 17: knit.
Row 18: knit (except on row 18 of the final/eighth wedge, which you’ll bind off instead).
Repeat rows 1 – 18 seven more times.
Finish with mattress stitch from outside of circle to inside. Cinch up the inner circle. Weave in ends.
