The Sage Vein Leaf is a single crochet leaf motif with a strong botanical look. A raised spine runs from tip to tip, and thick side veins fan out from it toward a soft cream edge. Open windows between the veins let light through, so the leaf looks like a pressed fern frond.
The palette is two calm colors: sage green for the leaf and cream for the border. The cream border has two textures, a smooth inner band and a beaded rope edge finished in crab stitch. A tiny picot sharpens each tip.
This pattern uses US crochet terms. The finished leaf measures about 4.5 in wide x 7.5 in long (11.4 x 19.1 cm) from picot tip to picot tip after blocking.
Construction is simple. You work around both sides of a foundation chain to make the spine. One round of graduated tall stitches forms the veins and windows, and one green round closes the edge. Two cream rounds finish the leaf. The whole leaf is one piece, so there is nothing to join.

– Ruler or tape measure
Abbreviations (US Terms)
- ch: chain
- sl st: slip stitch
- sc: single crochet
- hdc: half double crochet
- dc: double crochet
- tr: treble crochet (yo twice)
- dtr: double treble crochet (yo 3 times, insert hook, pull up a loop, [yo, pull through 2 loops] 4 times)

Special stitch: Reverse single crochet (rev sc). Work from left to right (right-handed). Insert the hook into the next stitch to the right, yo, pull up a loop, yo, and pull through both loops. Each rev sc makes one bead of the rope edge.
Vein: 2 stitches of the stated height worked into the same stitch. The pair spreads slightly at the top, which makes the vein thick and ropy.
Gauge and Checkpoints
Gauge: 16 sc x 18 rows = 4 in (10.2 cm) in sc with Color A and a 5.0 mm hook. That works out to 4 sc per 1 in (2.5 cm).
This is a single piece, so Rounds 1–3 work well as your test. Crochet them, lay the leaf flat without stretching, and check:
- After Round 1: the spine is 5.5 in (14.0 cm) long, not counting the tip chains, and about 0.5 in (1.3 cm) wide.
- After Round 2: the leaf is about 3 in (7.6 cm) wide across the dtr veins and about 6 in (15.2 cm) long.
- After Round 3: the leaf is 3.5 x 6.25 in (8.9 x 15.9 cm).
- After Round 5: the leaf is 4.5 x 7.5 in (11.4 x 19.1 cm) after blocking.
If your leaf is too big: if the spine is more than 0.25 in (0.6 cm) over at Round 1, go down to a 4.5 mm hook and start again.
If your leaf is too small: if the spine is more than 0.25 in (0.6 cm) short, go up to a 5.5 mm (I-9) hook.
Check length first. Width depends on your personal tension for tall stitches, so small width differences are normal and even out in blocking.
Leaf Center (Color A, Sage Green)
The two tips have names so you can track them. Tip A is the top tip of the leaf. Tip B is the bottom tip, where each round starts and ends.
Foundation: With Color A, ch 23.
Round 1 (spine): Sc in the 2nd ch from the hook and in each ch across (22 sc). Ch 2 for Tip A. Rotate the work and sc in each of the 22 free loops on the other side of the foundation chain. Ch 2 for Tip B, then sl st to the first sc.
Count: 44 sc (22 per side) + 2 ch-2 tip sps.
Place a marker in each tip ch-2 sp. The doubled line of sc around the chain forms the raised, braided center vein.
Round 2 (veins and windows): Ch 1 (does not count as a stitch). Work Side 1 as follows, starting in the same sc as the join:
2 hdc in first sc, [ch 3, sk 2 sc, 2 dc in next sc], [ch 3, sk 2 sc, 2 tr in next sc], [ch 3, sk 2 sc, 2 dtr in next sc], [ch 3, sk 2 sc, 2 dtr in next sc], [ch 3, sk 2 sc, 2 tr in next sc], [ch 3, sk 2 sc, 2 dc in next sc], [ch 3, sk 2 sc, 2 hdc in last sc].
The veins land on spine stitches 1, 4, 7, 10, 13, 16, 19, and 22. That gives 8 veins and 7 windows per side.
At Tip A, work (sc, ch 2, sc) in the ch-2 sp. Repeat the Side 1 sequence exactly along Side 2. At Tip B, work (sc, ch 2, sc) in the ch-2 sp, then sl st to the first hdc.
Count: 16 vein sts per side (32 total) + 4 tip sc = 36 sts, plus 14 ch-3 windows and 2 ch-2 tip sps.
The vein heights rise from hdc to dtr and drop back down. This creates the pointed oval outline, with the tallest veins at the widest part of the leaf. The ch-3 spaces become the long slit windows.
Round 3 (green edge, conversion round): Ch 1.
- Side 1: sc in each of the first 2 hdc, then [3 sc in next ch-3 sp, sc in each of next 2 sts] 7 times (37 sc).
- Tip A: sc in the next tip sc, (sc, ch 2, sc) in the ch-2 sp, sc in the next tip sc.
- Side 2: repeat Side 1 (37 sc).
- Tip B: sc in the next tip sc, (sc, ch 2, sc) in the ch-2 sp, sc in the next tip sc.
Sl st to the first sc. Fasten off Color A.
Count: 36 sts worked 1 per existing st + 42 sc added in the windows (14 x 3) + 4 new tip sc = 82 sc, plus 2 ch-2 tip sps.
Per side, between the tip sps: 1 + 1 + 37 + 1 + 1 = 41 sc.
Checkpoint: 3.5 x 6.25 in (8.9 x 15.9 cm). Each window should sit open without puckering. If the edge cups, your window stitches are too tight. Work them looser rather than adding stitches.
Border (Color B, Cream)
Border gauge: keep the same 4 sc per 1 in (2.5 cm) along the edge. Each of the 2 border rounds adds about 0.25 in (0.6 cm) of depth, so the border is 0.5 in (1.3 cm) deep in total.
Round 4 (smooth band, conversion round): Join Color B with a sl st in the Tip B ch-2 sp. Ch 1 and work (sc, ch 2, sc) in the same sp.
- Side 1: sc in each of the next 14 sc, 2 sc in next sc, sc in each of the next 11 sc, 2 sc in next sc, sc in each of the next 14 sc. That covers all 41 stitches and makes 43 sc.
- Tip A: (sc, ch 2, sc) in the ch-2 sp.
- Side 2: repeat Side 1 (43 sc).
Sl st to the first sc.
Count: 82 sts worked 1 per existing st + 4 side increases + 4 tip sc = 90 sc, plus 2 ch-2 tip sps.
Per side, between the tip sps: 1 tip sc + 43 + 1 tip sc = 45 sc.
Round 5 (beaded rope edge, trim round): Ch 1. Working from left to right, rev sc in the same st as the join and in every sc around. When you reach each tip ch-2 sp, work (rev sc, ch 3, rev sc) in it. Sl st to the first rev sc and fasten off.
Count: 90 sts worked 1 per existing st + 4 tip rev sc = 94 rev sc, plus 2 ch-3 picots.
Per side, between the picots: 45 + 2 = 47 rev sc.
Why the math works: the leaf’s outline curves outward, so each new round sits on a longer edge than the one before.
- Round 4: each long side gains about 0.5 in (1.3 cm) of length. The 2 increases per side add about 0.5 in (1.3 cm) of stitches at 4 sc per inch, which absorbs that extra length. They sit at the widest part, where the curve is strongest. The (sc, ch 2, sc) at each tip adds 1 sc to each end of each side, which keeps the points sharp instead of rounding them off.
- Round 5: crab stitch is naturally compact, so 1 rev sc per stitch lies flat without increases. The only extra stitches are at the tips, where the picots need room.
Final Blocking
- Weave in all ends inside stitches of the same color: green tails along the spine and cream tails inside Round 4.
- Soak the leaf in cool water, then press out the excess in a towel. Do not wring it.
- Lay it right side up on the blocking mat.
- Pin Tip B, then pin Tip A 7.5 in (19.1 cm) away in a straight line, stretching the picots to points.
- Pin each side at the widest point so the leaf is 4.5 in (11.4 cm) across.
- Ease each side vein so it angles slightly up toward Tip A. Open each window into a clean slit, and pin through any window that wants to close.
- Pin the rope edge every 0.5 in (1.3 cm) into a smooth curve.
- Let the leaf dry completely before you unpin it.
Final Quality-Control Checklist
- The leaf measures 4.5 x 7.5 in (11.4 x 19.1 cm).
- The two halves are mirror images, with 8 veins and 7 windows per side.
- The spine runs straight from tip to tip without twisting.
- The dtr veins sit opposite each other at the widest point.
- Round 3 has 82 sc, Round 4 has 90 sc, and Round 5 has 94 rev sc.
- Both tips come to clean points, each with a ch-3 picot.
- The rope edge lies flat, with no ruffling and no cupping.
- No ends show on the front.
Troubleshooting
- The spine curves or twists: your foundation chain was tighter than your sc. Chain with a hook one size larger, or chain more loosely.
- The windows are closed or puckered: your ch-3 spaces are too tight. Chain loosely and pull each dtr up to its full height.
- The leaf is round instead of pointed: check the (sc, ch 2, sc) at each tip in Rounds 2–4, and pin the tips firmly when blocking.
- Round 4 ruffles: you added extra increases. Recount to 45 sc per side.
- Round 4 cups: your tension is tight. Loosen up, or add 1 more increase per side at the center of each side.
- The crab stitch looks flat or twisted: make sure you are working left to right, and keep each loop loose.
- The two sides don’t match: one side’s veins were worked at different heights. Count the vein sequence on each side.
Care
Hand wash in cool water with a mild soap. Reshape the leaf and dry it flat, re-pinning the tips if needed.
Final Notes
The measurement chain is short and easy to check:
- The spine is 5.5 in (14.0 cm) at 4 sc per 1 in (2.5 cm).
- The vein round brings the leaf to about 3 x 6 in (7.6 x 15.2 cm).
- The green edge finishes the center at 3.5 x 6.25 in (8.9 x 15.9 cm).
- Two cream rounds add 0.5 in (1.3 cm) per side, for a blocked leaf of 4.5 x 7.5 in (11.4 x 19.1 cm).
If you hit each checkpoint, the counts of 44, 36, 82, 90, and 94 will fall into place and your leaf will match the one shown. Keep your tension even on the tall veins, block patiently, and enjoy your sage leaf.
Happy crocheting!
