Crocheted cream letter F with ornate shell stitches, purple flowers, and a gold ring on linen.

Lavender Lace Monogram Letter F Keychain Crochet Pattern

by

This little monogram keychain is a solid letter F made from stacked lace fans, each one opening upward like a small seashell. A corded crab-stitch edge outlines the letter, and a gold ring at the top makes it a charm for keys or bags.

The letter is worked in soft cream cotton. A small cluster sits at the bottom-left corner: one deep lavender flower, one lighter lilac flower, pale yellow French-knot centers, and three sage green leaves. The look is light and romantic, and it makes a quick personal gift.

All instructions use US crochet terms. The finished letter measures 3.1 in (7.9 cm) wide and 4.6 in (11.7 cm) tall, not counting the hardware.

You work the letter flat in rows from the bottom of the stem upward, using a 2-row fan repeat. Chain extensions add the middle arm and the top bar. Two border rounds frame the shape, and then you sew on the flowers and leaves.

  • Deep lavender (large flower): 2 g / 7 m
  • Light lilac (small flower): 2 g / 7 m
  • Sage green (leaves): 2 g / 7 m
  • Pale yellow (centers): 1 g / 3 m

These quantities include a margin for a gauge test and sewing tails.

Tools: 2.5 mm hook, tapestry needle, gold jump ring 1/4 in (0.6 cm), gold split key ring 1 in (2.5 cm), 2 pairs of flat-nose pliers, rustproof pins, foam blocking board, spray bottle, ruler.

Abbreviations (US Terms)

  • ch – chain
  • sl st – slip stitch
  • sc – single crochet
  • hdc – half double crochet
  • dc – double crochet
  • sc2tog – single crochet 2 together
  • st(s) – stitch(es)
  • sk – skip
  • MR – magic ring
  • RS / WS – right side / wrong side

Reverse single crochet (crab stitch): With RS facing, work from left to right. Insert the hook in the next st to the right, pull up a loop, yarn over, and draw through both loops.

Gauge and Checkpoints

Gauge: 7 sts = 1 in (2.5 cm) wide. One fan pair (1 fan row + 1 fill row) = 0.5 in (1.3 cm) tall. Row 1 = 0.2 in (0.5 cm) tall.

Test first: Work Rows 1–5. The test piece should measure 1 in (2.5 cm) wide x 1.2 in (3.0 cm) tall, give or take 0.1 in (0.3 cm). If it matches, keep going, because this is the start of your letter.

Checkpoints (unblocked, lightly flattened):

  • After Row 11: 1 in (2.5 cm) wide x 2.7 in (6.9 cm) tall
  • After Row 13: 1.9 in (4.8 cm) wide at the arm; 3.2 in (8.1 cm) tall
  • After Row 15: 3.7 in (9.4 cm) tall
  • After Row 17: 2.7 in (6.9 cm) x 4.2 in (10.7 cm)
  • After the border: 3.1 in (7.9 cm) x 4.6 in (11.7 cm)

Too big? Switch to a 2.25 mm hook. Too small? Switch to a 2.75 mm hook. If only the height is off, check your dc. Pull each loop up fully and don’t tug it short.

Letter F Body

With cream. The RS faces you on even rows. Seen from the RS, every odd row ends at the right edge, so each chain extension grows to the right.

Stem

Foundation: Ch 8.

Row 1 (WS): Sc in 2nd ch from hook and in each ch across, turn. (7 sts)

Row 2 (RS, fan row): Ch 1 (does not count as a st), sc in first st, sk 2, 5 dc in next st, sk 2, sc in last st, turn. (7 sts: 1 fan)

Row 3 (WS, fill row): Ch 3 (counts as dc), dc in next dc, hdc in next dc, sc in center dc, hdc in next dc, dc in next dc, dc in last sc, turn. (7 sts)

The fill row has tall stitches at the edges and a short stitch in the center. This levels the arched top of the fan, so the next fan stacks directly above it.

Rows 4–11: Repeat Rows 2–3 four times. (7 sts; 5 fans total) Do not turn after Row 11.

Middle Arm

Ch 7 (1 turning ch + 6 base chains).

Row 12 (RS): Sc in 2nd ch from hook, sk 2 ch, 5 dc in next ch, sk 2 ch, sc in last st of Row 11, sk 2, 5 dc in next st, sk 2, sc in last st, turn. (13 sts: 2 fans sharing the middle sc)

Row 13 (WS): Ch 3 (counts as dc), dc in next dc, hdc in next dc, sc in center dc, hdc in next dc, dc in next dc, dc in shared sc, dc in next dc, hdc in next dc, sc in center dc, hdc in next dc, dc in next dc, dc in last sc, turn. (13 sts: 7 + 6)

Upper Stem

Row 14 (RS): Sl st in each of first 7 sts, ch 1, sc in same st as last sl st, sk 2, 5 dc in next st, sk 2, sc in last st, turn. (7 sts: 1 fan; the 7 sl sts are not counted)

The slip stitches close off the arm without adding height. They also give the border a base along the arm’s top edge.

Row 15 (WS): Work as Row 3. (7 sts) Do not turn.

Top Bar

Ch 13 (1 turning ch + 12 base chains).

Row 16 (RS): Sc in 2nd ch from hook, sk 2 ch, 5 dc in next ch, sk 2 ch, sc in next ch, sk 2 ch, 5 dc in next ch, sk 2 ch, sc in last st of Row 15, sk 2, 5 dc in next st, sk 2, sc in last st, turn. (19 sts: 3 fans; 12 chain-based + 7 stem)

Row 17 (WS): Ch 3 (counts as dc), dc in next dc, hdc in next dc, sc in center dc, hdc in next dc, dc in next dc, dc in next sc; repeat from * twice more. (19 sts: 1 + 3 x 6)*

Fasten off.

Flowers and Leaves

Large flower (deep lavender): MR, ch 1, 5 sc in ring, sl st to first sc. (5 sts) Then (ch 2, 3 dc, ch 2, sl st) all in each sc. (5 petals) Fasten off with an 8 in (20.3 cm) tail. Size: 0.9 in (2.3 cm).

Small flower (light lilac): MR, ch 1, 5 sc in ring, sl st to first sc. (5 sts) Then (ch 1, 3 hdc, ch 1, sl st) all in each sc. (5 petals) Fasten off with an 8 in (20.3 cm) tail. Size: 0.75 in (1.9 cm).

Centers: With pale yellow, work one French knot (3 wraps) in the middle of each flower.

Leaf (make 3, sage green): Ch 7. Sc in 2nd ch from hook, hdc in next ch, dc in next 2 ch, hdc in next ch, (sc, ch 2, sc) in last ch for the tip. Working along the other side of the chain: hdc in next ch, dc in next 2 ch, hdc in next ch, sc in last ch, sl st to first sc. (12 sts + ch-2 tip) Fasten off with a 6 in (15.2 cm) tail. Length: 0.8 in (2.0 cm).

Border

Border gauge: At row ends, work 3 sc per fan pair: 1 sc at the end of each fan row and 2 sc at the end of each fill row. Work 1 sc in each chain or stitch top. Work 3 sc in each outer corner st. Work 1 sc2tog at each inner corner. In this border, side counts exclude the corner stitches, which are listed separately.

Round 1 (RS): Join cream in the top of the beginning ch-3 of Row 17 (top-left corner), ch 1.

  1. Top-left corner: 3 sc in same st
  2. Left edge, Rows 17 to 1: 25 sc (8 pairs x 3 + 1)
  3. Bottom-left corner: 3 sc in first foundation ch
  4. Bottom edge: 5 sc
  5. Bottom-right corner: 3 sc in last foundation ch
  6. Stem right edge, Rows 1–11: 16 sc (1 + 5 x 3)
  7. Inner corner: sc2tog over first 2 arm base chains
  8. Arm underside: 3 sc
  9. Arm corner: 3 sc in last arm base chain
  10. Arm end, Rows 12–13: 3 sc
  11. Arm corner: 3 sc in first sl st of Row 14
  12. Arm top: 5 sc in next 5 sl sts
  13. Inner corner: sc2tog over last sl st and end of Row 14
  14. Row 15 end: 2 sc
  15. Inner corner: sc2tog over first 2 top-bar base chains
  16. Top bar underside: 9 sc
  17. Top bar corner: 3 sc in last base chain
  18. Top bar end, Rows 16–17: 3 sc
  19. Top-right corner: 3 sc in last st of Row 17
  20. Top edge: 17 sc

Sl st to first sc. Total: 112 sts.

Round 2: Ch 1, crab stitch in each st around. Sl st to join and fasten off. (112 sts)

Why the math works: The ten sides use 88 sts (25 + 5 + 16 + 3 + 3 + 5 + 2 + 9 + 3 + 17). The 7 outer corners add 21, and the 3 inner sc2tog add 3, for 112 in total. Every base stitch is used exactly once:

  • Foundation: 1 + 5 + 1 = 7
  • Arm chains: 2 + 3 + 1 = 6
  • Top-bar chains: 2 + 9 + 1 = 12
  • Row 17: 1 + 17 + 1 = 19
  • Arm slip stitches: 1 + 5 + 1 = 7

Three sc per 0.5 in (1.3 cm) of row ends sits a little below the 7 sts per 1 in (2.5 cm) across the rows. That slight difference keeps the long sides from rippling. The two rounds add 0.2 in (0.5 cm) per side, so 2.7 in (6.9 cm) becomes 3.1 in (7.9 cm) and 4.2 in (10.7 cm) becomes 4.6 in (11.7 cm).

Final Blocking

  1. Spray the letter until it is evenly damp.
  2. Lay it RS up on the blocking board.
  3. Pin all 7 outer corners first, checking 3.1 in (7.9 cm) across the top and 4.6 in (11.7 cm) down the left edge.
  4. Pin each inner corner so the edges are square.
  5. Ease each fan into an even, open arc with your fingertip.
  6. Let it dry completely. Block the flowers and leaves flat at the same time.
  7. Unpin, then sew on the appliqués. Attach the large flower so it overlaps the bottom-left corner. Tuck the small flower just below and to its right. Place one leaf above the large flower, one to the right of the small flower, and one below the bottom-left corner.
  8. Open the jump ring sideways with two pliers. Pass it through Round 1 at the top edge, about 0.5 in (1.3 cm) from the top-left corner. Add the key ring, then close the jump ring.

Final Quality-Control Checklist

  • 5 fans in the lower stem, 2 across the arm, 1 in the upper stem, and 3 across the top bar
  • Round 1 counts 112 sts
  • Corners are crisp, and inner corners lie flat
  • The crab-stitch edge is even all the way around
  • Size is 3.1 in (7.9 cm) x 4.6 in (11.7 cm)
  • Appliqués are stitched through the letter, and no stitches show on the WS
  • The jump ring is fully closed with no gap
  • All ends are woven in and trimmed

Troubleshooting

  • Fans lean sideways: Make sure the 5 dc go in the center st, with exactly 2 sts skipped on each side.
  • Top of the stem is bumpy: Recheck the fill row: dc at the edges, hdc next to them, and sc in the center.
  • Border ruffles: Your edge stitches are too loose. Go down 0.25 mm for the border only.
  • Border cups: Add 1 sc at each long-side row end, and only there.
  • Gap at the arm: Work the sc2tog legs firmly into the chain base.
  • Flowers flop: Tack the petal tips down as well as the center.

Care

Hand wash in cool water, press out the water in a towel, and dry flat. Remove the key ring before washing.

Final Notes

The measurement chain is simple. A 7-st stem is 1 in (2.5 cm) wide. Eight fan pairs plus the base row make 4.2 in (10.7 cm) of height. Repeats of 13 and 19 sts give 1.9 in (4.8 cm) at the arm and 2.7 in (6.9 cm) at the top bar. A 112-st, two-round border adds 0.2 in (0.5 cm) per side, bringing the letter to 3.1 in (7.9 cm) x 4.6 in (11.7 cm). Check each stage as you go, and your F will come out right.

Happy crocheting!
