TL;DR
Write the sweater brief in measurements and gauge, approve a knitted swatch per colourway, then measure the washed sample before the size grading and care label are fixed.
The brief comes before the artwork
A Christmas sweater project fails at the brief stage far more often than at the knitting stage. Before artwork is discussed, settle the size run, the retail season, the fibre direction and the weight you expect the garment to have in the hand. A buyer who asks for a warm winter jumper and a buyer who specifies a gauge and a target weight will receive very different samples from the same supplier.
Write the brief as a list of numbers rather than adjectives: chest width, body length, sleeve length and tolerance per size, plus the pack ratio. Suppliers quote against numbers, and those numbers become the standard that every later sample is measured against. If you are still choosing shapes, the Christmas sweater series lists styles by item number.

Knit structure and gauge change the quote
Three production routes dominate. Flat bed knitting produces shaped panels, which suits jacquard patterns and reduces cutting waste. Circular knitting produces a tube, which suits all-over stripes and simple colour blocks. Cut and sew starts from finished knit fabric and is the practical route when the design needs a print rather than a knitted motif.
Gauge describes the fineness of the knit and drives both weight and detail. A finer gauge carries small motifs and lettering cleanly, while a coarser gauge gives texture and a heavier hand but loses fine detail. Ask for the gauge in writing, because chunky means different things to different buyers.

Artwork, repeats and colour control
Jacquard artwork has to be rebuilt as a stitch grid rather than simply downscaled. Small type, gradients and thin outlines usually disappear in the knit. Ask for the repeat width and height in stitches and in centimetres before the sample is made, so you know how many repeats fit across the chest and where the design breaks at the side seam.
For colour, agree a reference for each yarn and ask for a knitted swatch instead of a digital proof. A screen cannot show how two yarns read next to each other, and a red that looks warm on a monitor can read orange in a wool blend.
Fibre, labelling and care claims
Fibre content is a legal statement in most markets rather than a marketing choice. In the United States, the Textile and Wool Acts set out how fibre content, country of origin and care information are disclosed, and the CPSC clothing guidance covers apparel questions including flammability. Confirm the final composition per colourway, because a two-tone design can use different yarns.
Care claims follow the fibre. A sweater described as machine washable needs a test wash at the stated temperature before the wording goes on the label, since shrinkage or pilling found after the order ships cannot be fixed with a changed sentence.
Shrinkage, fit and size grading
Knitted garments move. Ask what shrinkage allowance the pattern carries and whether the sample was measured before or after the first wash. Measure body length, chest width and sleeve length on the washed sample, and set the tolerance in centimetres rather than as a percentage of the size.
Grading follows the fit you approve. A unisex body that is simply scaled up usually becomes long and narrow at the top of the range, so check the largest size on a person or a form, not only on paper.
Sample approval and the order checklist
Approve one sample per colourway with the measurement sheet attached, and keep it sealed. Every later question about colour, hand or fit can then be answered by comparison instead of memory. The checklist below is the minimum record for a repeat order.
- Fibre composition and gauge recorded per colourway
- Repeat size stated in stitches and in centimetres
- Knitted swatch approved for each yarn
- Shrinkage allowance with washed measurements
- Size grading checked on the largest size
- Care label wording tested against the fibre
- Pack ratio and carton plan agreed
- Approved sample sealed and retained
