How to Do Entrelac Knitting

Entrelac looks like magic. The fabric appears woven, with squares and rectangles interlocking at right angles to each other, creating a basketweave or quilt-like texture. Seeing it for the first time, most knitters assume it's advanced beyond their current skill level. The reality is different: entrelac is made one small square at a time, and each square is just a simple rectangle of garter or stockinette. The complexity is structural, not technical.

If you can knit, purl, pick up stitches along an edge, and do a basic decrease, you can knit entrelac. What you need is the patience to understand how the squares connect before you start, and a willingness to work through the first tier before the structure clicks into place.

What Entrelac Actually Is

The word entrelac comes from the French for "interlaced." The fabric is built from a grid of small squares (typically 8–12 stitches and 8–12 rows per square, depending on your yarn weight), where each tier of squares runs perpendicular to the previous tier. The squares aren't seamed together — they're knitted directly onto each other by picking up stitches along the edge of the square below.

The result is a fabric with genuine three-dimensional texture, significant drape, and a visual interest that changes as you look at it from different angles. Because each square is worked separately, entrelac also allows each square to shift colour if you're using a yarn with long colour gradients — each small rectangle picks up a different segment of the colourway, creating a mosaic of colour without any deliberate colour-changing from you.

Yarn Choice for Entrelac

Entrelac works in any weight, but DK and worsted weights (3.5–4.5 mm needles) are most forgiving for learning. The fabric will be heavy enough to show the structure clearly but light enough to handle comfortably.

For colour interest, long-repeat gradient yarns are famous in the entrelac world. Malabrigo Rios, Noro Silk Garden, or any hand-dyed skein with gradual colour transitions will create a stained-glass effect with almost no effort on your part. Each square absorbs 2–4 metres of yarn, so the colour shifts as the squares progress.

For learning, use a solid or semi-solid yarn in a light colour. You need to see the structure of the stitches clearly while you're learning to pick up along edges and work the join decreases.

The Base Tier

Entrelac begins with a base tier of rectangles worked along the cast-on edge. These base rectangles are slightly different from the regular squares — they're typically worked as triangles to create a straight bottom edge, or as full rectangles if you're making something where a stepped bottom edge is acceptable (like a bag).

For a clean straight edge (most patterns use this), you work base triangles:

1. Cast on 2 stitches.
2. Row 1: Knit to last stitch, knit into front and back (kfb). Turn.
3. Row 2: Purl back.
4. Continue, adding one stitch on each RS row via kfb, until you have 10 stitches (for a 10-stitch entrelac).
5. Do not turn after the final row — this triangle is complete. Slide to the right and begin the next base triangle from the live stitches still on the left needle.

Repeat across the cast-on edge until all your base triangles are complete. You now have a row of stepped triangles sitting on the cast-on edge, each with 10 live stitches, waiting for the first tier of squares.

The First Tier of Squares

Squares in the first tier are worked by picking up stitches along the side edge of a base triangle, then joining to the next base triangle with a decrease on each RS row.

1. Pick up and knit 10 stitches along the side edge of the first base triangle (one stitch per two rows of the triangle edge). These are your square stitches.
2. Row 1 (WS): Purl back across the 10 stitches.
3. Row 2 (RS): Knit 9, then work an ssk using the last picked-up stitch and the first live stitch from the adjacent base triangle (the stitch you're joining to). Turn.
4. Repeat rows 1–2 until all 10 stitches from the adjacent triangle have been consumed by the joins. The square is complete.

You've just knitted one entrelac square — a 10-stitch, 20-row rectangle attached to the triangle below it and joined to the triangle beside it. Now pick up stitches along the next available edge and repeat.

Alternating Tiers

After the first tier of squares, the second tier runs in the opposite direction. You pick up stitches along the side edge of a first-tier square and join to the adjacent first-tier square as you work. Each tier alternates which direction the stitches run, which is what creates the woven appearance.

On alternating tiers, the join decrease changes direction too — you'll use k2tog instead of ssk, or vice versa, depending on which side the join falls. Your pattern will specify this, and it becomes instinctive after a few tiers.

The Top Edge

Just as the base tier uses triangles to create a straight bottom edge, the top tier uses triangles to create a straight top edge. Top triangles decrease one stitch per RS row (instead of increasing) and join to the adjacent square as they go, consuming stitches until only one remains. This stitch is bound off, and you move to the next top triangle.

Good First Entrelac Projects

A small entrelac bag is perfect for learning because the structure works naturally in the round (no cast-on or bind-off edge management for a bag body) and the bottom is forgiving. An entrelac cowl worked in the round is also excellent — it eliminates edge triangles entirely since you're working in a continuous round of squares. A standard 80-stitch cowl on 4 mm needles with 10-stitch squares gives you 8 squares per tier, which is enough to see the pattern develop without taking too long.

Once you've completed one entrelac project all the way through — base tier, several regular tiers, and top tier — the structure becomes completely intuitive. The pick-up and join process feels mechanical in the best sense: reliable, predictable, and satisfying.
