Another pattern from an earlier design - a rosette motif. The pattern uses shuttle and ball.
The rosette centre, you'll need 90cm size 20 thread on the shuttle wound CTM.
Begin with a ring R(4-4-4-4-4-4), and reverse work.
The next rounds are all chains working round this centre ring.
Make a mock picot at the start of Round 1 and continue with the chain C(5+5+5+5+5+5), making a lock join to the picots of the centre ring. End with a lock join to the mock picot at the start of the round.
Continue with the other rounds for the rosette following the ds count shown in the chart.
For the final round, you'll need about 180cm of thread in the shuttle wound CTM.
Begin with R(5+5), join to the last picot in one segment of the rosette. Do not reverse.
R(5+5), join to the first picot of the next segment of the rosette, reverse work.
C(2-4-4-4-4+), lock join to the next picot,
(*) C(4-4-4-4-2), reverse work.
Repeat the first two rings, joining to the next two picots of the rosette respectively, reverse work.
C(2+4-4-4-4), join to the last picot of the previous chain.
Continue from (*) to complete the round.
Join up the motifs together to make a doily as in the picture below.
