Trellis by Britta Stolfus Rueschhoff is a classic baby cardigan featuring decorative cables, seed stitch and a cozy shawl collar. Originally published in Knitty in 2005, the design remains a popular choice for knitters who enjoy traditional texture and structured garment knitting.
The sweater is worked in pieces from the bottom up and then seamed together. Its most distinctive feature is the repeating trellis cable motif, which creates a rich textured surface across the body while the shawl collar gives the cardigan a timeless, polished look.
The complete Trellis pattern is still available free from its original publisher, Knitty.

A Classic Baby Cardigan With Trellis Cables
The feature that makes Trellis immediately recognizable is its all-over cable texture.
The cable motifs form repeated interlocking shapes across the knitted fabric, creating the visual effect of a trellis or lattice.
This gives the sweater much more depth than a plain stockinette cardigan while still keeping the overall design traditional and suitable for either boys or girls.
The 18-Row Cable Repeat
The central texture is built around an 18-row repeating cable pattern.
Although that sounds long compared with a simple rib repeat, cable patterns often become much easier once the structure begins to appear in the fabric. The growing cables themselves provide visual clues about where you are in the repeat.
It is still worth keeping a row counter nearby, especially during the first few repeats.
Seed Stitch Details
Trellis combines the cable pattern with seed stitch, which adds another layer of texture without competing with the main cable motifs.
Seed stitch alternates knit and purl stitches to create a small pebbled surface. In this design, it helps frame the more pronounced cable sections and gives the cardigan a carefully finished look.
The Shawl Collar
A shawl collar is one of the most attractive features of Trellis.
Unlike a simple ribbed neckline, the collar creates extra fabric around the neck and front opening, giving the sweater a warm, jacket-like appearance.
This style works especially well with the traditional cable texture because both elements give the cardigan a classic hand-knit character.
How Trellis Is Constructed
The cardigan is worked flat from the bottom up.
The individual garment pieces are knitted separately and then assembled with seams. This is a more traditional sweater-construction method than seamless top-down knitting.
Because the pieces are worked flat, knitters do not need to manage the entire garment in the round while following the cable pattern.
Seamed Construction
Trellis is not a seamless cardigan. The finished pieces must be joined during the finishing stage.
Good seaming can make a major difference in the final appearance of a cable sweater. Align the row edges carefully so that the texture remains balanced across the garment.
Blocking the individual pieces before final assembly can also help make the edges easier to match.
Baby Sizes
The original pattern includes three baby sizes:
- 6 months: approximately 21 in finished chest
- 12 months: approximately 23 in finished chest
- 18 months: approximately 25 in finished chest
The corresponding finished lengths are approximately 11, 12 and 13 inches.
As with any baby garment, use the finished measurements rather than relying only on the age label when selecting a size.
Yarn for the Trellis Cardigan
The original sample uses Rowan All Seasons Cotton, an Aran-weight cotton and acrylic blend.
The published yardage is approximately 392–490 yards / 358–448 meters, depending on size.
An Aran-weight yarn with clear stitch definition is a good choice for this project because the cable texture is one of the main visual features.
Choosing a Yarn Substitute
When substituting yarn, look for an Aran-weight yarn that can produce the required gauge while still showing cables clearly.
Very fuzzy yarns may hide some of the trellis definition, while a smooth wool, cotton blend or similarly structured yarn will usually make the cable crossings more visible.
For a baby garment, also consider softness, washability and durability.
Gauge
The published gauge is:
21 stitches and 28 rows = 4 in / 10 cm in the pattern stitch.
Gauge is especially important for a fitted garment because it directly affects the finished chest measurement and sleeve length.
Cable fabrics can behave differently from plain stockinette, so make your swatch in the actual pattern stitch whenever possible.
Needles
The original pattern recommends US 7 / 4.5 mm needles.
Treat that size as a starting point rather than a fixed requirement. Use whichever needle size allows you to match the published gauge with your chosen yarn.

Is Trellis Beginner Friendly?
Trellis is better suited to an intermediate knitter or a confident advanced beginner ready to learn garment construction and cables.
The project combines several skills at once: cable work, pattern tracking, shaping, seaming and collar finishing.
None of these techniques is unusually difficult on its own, but together they make the sweater more involved than a basic garter-stitch baby cardigan.
Tips for Better Cable Definition
Use a smooth yarn. Clear stitch definition helps the trellis motifs remain visible.
Keep cable tension even. Avoid pulling too tightly immediately after crossing stitches.
Track the 18-row repeat. A row counter can prevent accidental misalignment between garment pieces.
Block before seaming. This can help the cable fabric relax and make the garment pieces easier to join neatly.
Check cable orientation regularly. Catching a reversed cable crossing early is much easier than fixing it several repeats later.
Tips for Neater Seams
Before assembling the cardigan, lay out the blocked pieces and make sure the edges and pattern sections align correctly.
Use consistent tension while seaming. Pulling the seam too tightly can distort the cable fabric, while a very loose seam may create visible gaps.
Take particular care where sleeves meet the body, since bulky cable fabrics can create extra thickness at garment joins.
Is Trellis a Free Knitting Pattern?
Yes. Trellis by Britta Stolfus Rueschhoff is currently listed as a free knitting pattern.
The design was originally published by Knitty in its Spring 2005 issue, and the free pattern remains associated with that original publication.
Amazing Knitting therefore directs readers to the original Knitty pattern rather than to copied PDFs or unofficial downloads.

Why This Baby Cardigan Is Worth Knitting
Trellis is a strong choice if you want a baby sweater that feels more substantial and traditional than a very simple beginner cardigan.
The cables provide enough repetition to make the knitting interesting, while the seed stitch and shawl collar give the finished garment a polished, heirloom-style appearance.
It is also an excellent small-scale project for practicing techniques that transfer directly to adult cable sweaters, including chart reading, shaping, seaming and collar construction.
