Veining is the detail that separates amateur sugar flowers from professional ones. Those fine, natural-looking lines running through a leaf or petal give gumpaste work a realistic texture that flat, unveined pieces simply cannot match. In this tutorial, Chef Alan Tetreault of Global Sugar Art demonstrates the major types of veiners on the market — plastic, silicone, single-sided, and double-sided — and shows how to use each one. He also addresses the most common question customers ask: whether the veiner has to match the cutter size (it does not).


What You'll Need

  • Gum paste or fondant — in the colors needed for your leaves and petals
  • Leaf and petal cutters — various sizes (FMM rose leaf cutters, five-petal rose cutters, hydrangea cutters, etc.)
  • Veiners — at least one of the types demonstrated: JTB plastic veiners (by Cel Cakes), two-piece silicone veiners, First Impressions veining mats, or FMM veiners
  • Foam pad or sponge pad — for pressing paste into single-sided veiners and for thinning edges
  • Ball tool or medium cel pin — for thinning and frilling petal edges after veining
  • Small spatula — for lifting veined pieces off the veiner
  • Cornstarch pouch — for dusting the board to prevent sticking
  • Rolling pin — for rolling out gum paste
  • Aluminum foil — crumpled lightly to create a drying surface with natural curves
  • Petal dust (optional) — for highlighting veining details after drying (dark green works well on leaves)


Types of Veiners

▶ Watch this section (1:03)

Chef Alan walks through four main categories of veiners available on the market:

  1. JTB plastic veiners (Cel Cakes) — Single-sided plastic veiners that produce deep, well-defined veining. Non-stick, so gum paste and fondant release cleanly without any dusting.

  2. First Impressions silicone veining mats — Available as single-sided mats or with a press-back piece. Some sets include both leaf and petal patterns on the same mat.

  3. Two-piece silicone veiners (CK Products / Sunflower) — A top and bottom piece that sandwich the paste, producing veining on both sides. Ideal for wired flowers on wedding cakes where both sides of the leaf or petal will be visible.

  4. FMM single-sided veiners — Silicone or rubber-based veiners in specialty shapes. The blossom veiner is especially useful for hydrangeas, apple blossoms, and cherry blossoms. FMM also makes long, thin veiners suited to grass and seaweed effects, as well as orchid lip veiners.


Using JTB Plastic Veiners

▶ Watch this section (2:49)

  1. Roll out green gum paste thin and dust the board with cornstarch so the paste moves freely.
  2. Cut a leaf with the desired cutter — any size will work with a single veiner.
  3. Place the leaf on the veiner with the pointed tip toward the top, centering it along the main center vein.
  4. Lay a foam pad on top of the leaf and press down evenly. There is no need to press hard — moderate pressure produces a clean impression.
  5. Lift the leaf off with a small spatula. The paste should release without sticking.

💡 One veiner works for multiple cutter sizes. Chef Alan demonstrates cutting three different leaf sizes — large, medium, and small — and veining all three on the same JTB veiner. The key is to always position the leaf toward the top of the veiner where the veining detail is finest. Placing a small leaf at the bottom of the veiner will produce veins that look out of scale.


Thinning Edges and Drying Leaves

▶ Watch this section (5:18)

After veining, the edges of each leaf or petal can be refined for a more realistic finish:

  1. Place the veined piece on a foam pad.
  2. Use a ball tool or medium cel pin along the edges — half on the paste, half off the pad — and stroke back and forth to thin and soften the edges.
  3. This technique works for both wired and unwired leaves.

↪ Drying for a natural shape

  1. Take a piece of aluminum foil (the small sheets sold for wrapping baked potatoes work well) and lightly crumple it.
  2. Lay the veined leaves into the folds of the foil at different angles, pressing them down gently.
  3. Allow the leaves to dry in these curved positions. This produces a much more natural-looking result than a stiff, flat leaf.

💡 Highlight the veining with petal dust. Once the leaves are fully dry, brush on a contrasting shade of dark green petal dust to make the veining pop. The dust settles into the recessed vein lines and draws out the detail.


Using Two-Piece Silicone Leaf Veiners

▶ Watch this section (7:05)

Two-piece silicone veiners produce veining on both sides of the leaf — front and back. This matters most when making wired flower sprays for wedding cakes, where guests walk around the cake and see both sides of every leaf.

  1. Roll the gum paste slightly thicker than for single-sided veining. Thicker paste prevents the two halves from cutting through the center or crushing the edges.
  2. Cut the leaf and position it on the bottom half of the veiner, with the tip toward the top.
  3. Place the top half of the veiner on and press around the edges rather than the center. Pressing the center too hard can cut through thin paste.
  4. Open the veiner and peel out the leaf. It should be veined on both sides.

⚠️ Roll the paste a bit thicker when using two-piece veiners. If the paste is too thin, pressing the halves together can cut through the center or smash the edges. A slightly thicker piece holds up better and still produces clean detail.


Using Two-Piece Petal Veiners

▶ Watch this section (8:46)

Petal veiners work like leaf veiners, but the placement is different:

  1. Roll pink (or desired color) gum paste slightly thick and cut with a petal cutter.
  2. Look at the veiner's pattern — on a petal, the veining starts heavy at the base and fans outward, getting finer toward the edges.
  3. Place the petal at the bottom of the veiner (not the top like a leaf) so the heaviest veining aligns with the base of the petal.
  4. Press the top piece on and work around the edges.
  5. Remove and finish by frilling the edges with a ball tool on a cel pad before attaching to the cake or assembling into a flower.

💡 Leaf placement vs. petal placement: Leaves go tip toward the top of the veiner. Petals go base toward the bottom. This ensures the veining pattern runs in the correct botanical direction for each.


Veining Small Blossoms

▶ Watch this section (10:40)

The FMM blossom veiner has veins radiating from the center outward in a full circle, making it ideal for small multi-petal flowers.

  1. Roll paste thin and cut with a hydrangea cutter (or any small five-petal blossom cutter — apple blossom, cherry blossom, etc.).
  2. Center the cut blossom on the veiner.
  3. Press the top pad on, working around the outer edges rather than the center. The center will be covered by a stamen or small bumps, so the visible veining detail is along the petals.
  4. Peel off the blossom, thin the edges with a ball tool, and dry flat or on crumpled foil.

These can be used loose on a cake or wired into sprays.


Veining Five-Petal Rose Cutouts

▶ Watch this section (12:46)

For decorators using all-in-one five-petal rose cutters (available from FMM, JEM, PME, and others), a First Impressions veining mat works well:

  1. Roll gum paste and cut with the five-petal cutter. Make sure the paste moves freely on the board.
  2. Place the entire cutout in the center of the veining mat.
  3. Press the back piece on, working mostly on the petals rather than the center.
  4. The result is subtle, soft veining on both sides — appropriate for roses, which have very delicate petal texture compared to leaves.

The veined five-petal cutout can then be wrapped around a bud to build a rose. Each petal will carry realistic veining that elevates the finished flower from amateur to professional quality.

💡 Rose petals need soft veining, not deep veining. Unlike leaves — which have prominent, raised veins in nature — rose petals have very fine, shallow texture. The First Impressions mats produce exactly this kind of subtle detail.


Tips and Key Takeaways

💡 You do not need to match the veiner to the cutter. This is the most common question Chef Alan receives. A single veiner can handle multiple cutter sizes — just adjust the placement on the veiner. There is no need to buy a veiner for every cutter in the collection.

💡 Always position leaves toward the top of the veiner where the veining is finest and most detailed. Small leaves placed at the bottom will have veins that look too large.

💡 Use double-sided veiners for wired sprays and standing flowers where both sides of each leaf and petal will be visible — especially on wedding cakes.

⚠️ Cornstarch is your friend, but silicone veiners and JTB plastic veiners are naturally non-stick. Dust the cutting board, not the veiner itself — excess cornstarch in the veiner grooves can actually fill in the detail and reduce the veining quality.
