Notes
Step-by-step photo chart for the mandala coaster, rounds 7-10. Rnd 7 uses joined unfinished dc (dc dec across motifs) to create the openwork lattice; Rnd 10 is worked over Rnd 9 so the last colour frames the scallops.

Frequently asked questions
Which round is the tricky one?
Round 7. You work above the middle double crochet of each 3-dc group and join unfinished double crochets across neighbouring motifs to make the openwork lattice - the step photo for R7 is worth studying before you start.
Why does the last round look like it floats?
Round 10 is worked between the round 8 motifs and over the top of round 9, so the navy scallops sit in front of the previous round instead of on top of it.
Do I need all six colours?
No - the shape works in any colour order. The six-colour scheme just makes each round read separately, which is why the chart is coloured round by round.
