Two swaddles can both be labelled “100% cotton muslin, 47 × 47 inches” and feel like entirely different products.
This is the most common gap we see between a buyer and a manufacturer. The buyer specifies a size and a material. The manufacturer hears a size and a material. Neither party has said anything about the four variables that determine whether the finished blanket feels premium or thin, or whether it survives the tenth wash.
GSM — grams per square metre — is the weight of the fabric itself. It is the single most useful number for describing muslin, and the one most often missing from a brief.
A lighter gauze gives a drapey, airy blanket that folds down small. A heavier gauze gives a denser, more substantial hand feel that a customer perceives as better made. Neither is objectively correct — but a swaddle positioned at the top of a market's price band almost always needs the heavier fabric, because the first thing a customer does in a store is pick it up.
Where buyers get caught out is comparing GSM figures across suppliers who do not measure the same way, or after different finishing processes. Always ask whether the figure is quoted on the greige fabric or on the finished, washed product. Those two numbers are not the same, and the difference is not small.
Multi-layer muslin is built by stacking gauze panels and stitching them into a single piece. Two-layer, four-layer and six-layer are the usual configurations.
Layer count is not simply a measure of quality — it is a measure of warmth and weight. A four-layer swaddle built from a light gauze can be lighter than a two-layer swaddle built from a heavy one. Buyers who specify “4-layer” as a shorthand for “good” are specifying a construction rather than an outcome.
There is also a production risk hidden here. Layers have to stay aligned through cutting, stitching and packing. Where the alignment check is weak, a four-layer product can ship as a three-and-a-half-layer one, and nobody notices until a customer opens it. This is why we verify layer alignment at assembly rather than relying on the cutting ticket.
Muslin is a plain weave. Weave density — how many warp and weft threads per inch — sets how open or closed the fabric looks and how well it holds a printed design. A denser weave takes a crisper print. A more open weave reads as airier but blurs fine detail.
Yarn quality sits underneath that. Cotton that has been combed to remove short fibres produces a smoother, less pilly fabric. It costs more. On a product where the customer's main complaint category is “it went bobbly after a few washes”, it is usually money well spent.

Two identical rolls of gauze become noticeably different products after finishing.
If you want a quotation that reflects the product you have in mind, specify these five things:
That last item matters more than buyers expect. Told the target price, a manufacturer can propose a construction that hits it. Told only a specification, a manufacturer can only tell you what that specification costs — which is frequently not what the buyer had in mind.
