I designed this pattern for a teacup doily-- a doily to place on the saucer, under a teacup.
Here's the pattern:

7-Point Star Teacup Doily:

Special Stitch: Picot-- ch 3, sl st in first ch

Begin doily: 

Ch 5, join with sl st in first ch to make ring.

Ch 1, 14 sc in ring;  join in beg ch.

Rnd 1:

Ch 4,  * sk 1 st, sc in next st, ch 4 * repeat from * to * around.

Rnd:2

Ch 3, * sc in middle of ch-4, ch 3 * repeat from * to * around

Rnd 3:

Rnd 4:
