This pattern is also on the CrochetMe site, but I figured I'd repost it here.
This is a pattern for a rose choker. It was meant as a surprise present for a friend using leftover yarn from a project she asked me to do. The rose pattern was taken from the "Brier Rose" pattern by Jennifer Fletcher from Anticraft: Knitting, Beading and Stitching for the Slightly Sinister by Renée Rigdon and Zabet Stewart, and the leaf pattern is the "Basic Small Leaf" from Nicky Epstein's Crocheted Flowers. The body of the choker is of my own design.
* A small amount of baby weight cotton yarn in red and green (the smoother the better)
* 3.5mm crochet hook
* A pretty button (about 3/4" in diameter) in a complementary colour (I used a red button).
The choker band is a little less than an inch (2.5cm) wide, and it should be long enough to fit snugly around your neck. The rose and leaves can be any size you want.
I got approximately 14 sts per 2" (5cm), but since the number of stitches you begin with is dependent on the circumference of your neck, it's better just to go with that and not worry too much about gauge.
make a chain ribbon the length of the circumference of your neck with an even number of ch.
row 1: sc in 2nd ch from hook, sc in each ch to end, ch 3, turn.
row 2: *skip 1st st, dc in 2nd st, dc in 1st st, making an X, rep from * to end, ch 1, turn.
row 3: sc in each sc across, 2sc in ch 3 from row 2, ch 8, 2 sc in ch 3, fasten off.
leaf (green, make two):
row 1: sl st in 2nd ch from hook, in each ch, 1 sc, 1 hdc, 1 dc, 1 hdc, 1 sc, 3 sc in last ch, working around other side of chain in each ch, 1 sc, 1 hdc, 1 dc, 1 hdc, 1 sc, 1 sl st, join with sl st in first sl st.
row 2: working blo, sl st in each st to 3 sc group, sl st in first sc, ch 2, skip next sc, sl st in 3rd sc, sl st in each st to end. Join with sl st in first sl st. Ch 4 for stem.
make adjustable ring
rnd 1: 5sc into adj ring, join, ch1 
rnd 2: sc in each st around, join, ch1 
rnd 3: 2 sc in each st around, join, ch1 
rnd 4: working flo, *(sc, ch1, dc, ch1, sc) in next st, sl st in next st, rep from * around (5 petals)
rnd 5: working blo, *sc in next st, 2 sc in next st, rep from * around, join, ch1 
middle and outside petals:
rnd 6: working flo, *(sc, hdc, dc) in next st, (dc, hdc, sc) in next st, sl st in next st, rep from * around, ch 1 (5 petals)
rnd 7: working blo, *(hdc, dc, tr) in next st, (tr, dc, hdc) in next st, sl st in next st, rep from * around. (5 petals)
Sew in ends, sew leaves and rose to center of choker, and sew the button to the end of the choker, opposite the button loop.
