About this pattern
A flat, single-panel lounge sweater built entirely from double crochet (UK: treble crochet) mesh, worked back and forth from a starting chain sized in multiples of 6 plus 4. Sleeves are formed mid-pattern by chaining outward from the body rather than being sewn on separately. Suits a US H / 5 mm hook and medium (size 4) weight yarn; a confident beginner comfortable with chain spaces can complete it in an evening or two.
This lounge sweater belongs to the double crochet (UK: treble crochet) family, built around alternating groups of stitches and chain-3 spaces that stack into an open, airy mesh. The lattice look comes from offsetting the chain spaces on each row so the gaps sit over the solid groups below, giving the fabric its checked texture without any increases or decreases.
The body is worked flat as a single rectangular panel from a foundation chain sized to a multiple of 6 plus 4, so the mesh repeat lines up cleanly edge to edge. Sleeve extensions are added midway through the body by chaining out from each side rather than seaming on separate pieces, and the finished garment is closed off with a plain single crochet (UK: double crochet) round at the sleeve openings and neckline.
Materials
- Size 4 medium weight yarn
- Crochet hook size H 5 mm

Body
Repeat rows 3 and 4 until reaching the desired body length.
Switch colors every two rows if using two yarn shades.
- Round 1
Sleeves Row 62 After completing a row 3 repeat, chain foundation stitches for sleeve extension on the left side.
- Round 2
Join yarn on the right side and chain foundation stitches for the other sleeve.Turn and work row 4 across the body and chains.Continue repeating rows 3 and 4 until sleeves measure your desired width.
- Round 3
Last Row Chain 1 and turn.
- Round 4
Single crochet in the next three stitches.
- Round 5
Double crochet in the next three skipped stitches of the prior row.
- Round 6
Single crochet in the next three stitches.Repeat this sequence across to form a solid edge.Fasten off.Second Panel Repeat the entire pattern to make a second matching panel.
Seaming Lay both panels together.
Seam the shoulders, leaving a neck opening.
Seam under the sleeves and down both sides.
Leave side slits if desired.
- Round 7
Finishing Work one round of single crochet around sleeve openings and the neckline for a clean look.
Making up
- Step 1Work one round of single crochet around sleeve openings and the neckline for a clean look.
Notes from the pattern
- Use a US H / 5 mm hook as listed; a smaller hook will tighten the mesh and pull the starting width in below 21 inches.
- Place a stitch marker at the start of each row while establishing the pattern, since it is easy to lose count of the multiple-of-6 repeat across a wide panel.
- Check gauge against the 21 inch starting width before committing to the full body length; the mesh stitch is forgiving in width but not in row height, so an early gauge swatch saves reworking the sleeve rows.

Stitches you will use
- Chain-space mesh (double crochet groups with chain-3 gaps) Forms the entire body fabric; watch that each chain-3 space sits centred over the previous row's stitches so the lattice stays even.
- Foundation chain in a fixed multiple The starting chain must land on a multiple of 6 plus 4; miscounting here throws off every mesh repeat that follows.
- Sleeve extension by chaining outward mid-piece the sleeve row, chains are added on both sides of the existing fabric rather than working a separate piece; keep chain counts identical on left and right for symmetry.
Troubleshooting
The mesh looks tight and boxy instead of open and airy.
This usually means the chain-3 spaces are being worked too snugly; relax tension slightly on the chain stitches and confirm the hook size matches H / 5 mm.
The sleeve openings sit uneven, with one side longer than the other.
The two sleeve extension chains were worked to different lengths; recount both foundation chains added at the sleeve row and match them exactly before continuing.
The finished edging round at the neckline or sleeves looks loose and gappy.
Single crochet (UK: double crochet) worked directly into an open mesh edge can splay; work each edging stitch slightly firmer than usual, or drop to a hook one size smaller for that one round only.
Substituting yarn
- Cotton, worsted (size 4) weight
- Produces a heavier, less stretchy mesh with crisper stitch definition; expect the panel to hang closer to the body and to need a firmer blocking to hold the lattice open.
- Wool-blend, worsted (size 4) weight
- Adds warmth and a softer drape to the mesh; the fabric will have more give across the multiple-of-6 repeat, so measure width after a few rows rather than relying on stitch count alone.
- Acrylic, worsted (size 4) weight
- Keeps the same hook size and stitch count as the original, with a lighter, more affordable result; the mesh will hold its shape well but drape slightly stiffer than a natural fibre.
Washing and care
- The materials list does not specify a fibre content beyond size 4 medium weight, so check the yarn band before washing; hand-washing in cool water and laying flat to dry is a safe default for most medium-weight yarns and protects the open mesh from stretching.
- Reshape the panel gently while damp, pinning the sleeve openings and neckline to their intended width so the chain-3 mesh dries lying flat rather than curling, then store folded rather than hung to keep the lattice from sagging out of shape.

FAQs
Questions
What hook size does this pattern use?
A US H / 5 mm hook, paired with size 4 medium weight yarn. Using a different hook size will change the 21 inch starting width, so it is worth swatching first.
Why does the starting chain need to be a multiple of 6 plus 4?
The mesh repeat is built on groups of stitches and chain-3 spaces that only line up correctly in multiples of 6, with the extra 4 chains accounting for the edge stitches. Any other chain count will throw the lattice off at the panel edges.
How are the sleeves added without separate seaming?
the sleeve row, foundation chains are added directly onto each side of the existing body panel, then worked across on the following row. This keeps the sweater as one continuous piece rather than requiring set-in sleeves.
Is it necessary to change colours every two rows?
No, the colour change is optional and only applies if working with two yarn shades. The mesh pattern itself works identically in a single colour throughout.
How is the neckline finished once the body is complete?
A single round of single crochet (UK: double crochet) is worked around both the sleeve openings and the neckline. This tidies the mesh edges into a clean, non-curling finish.
