From Made-to-Order Sewing to Batch Production
What changes when you go from sewing garments one at a time to batch production: sewing patterns, spreading, sizes, costs and how work is organized.
It's not sewing faster: it's sewing differently
Sewing to order and batch production are two trades that share the machine and little else. In made-to-order work, each garment is picked up, cut and sewn from start to finish: the time goes into the transitions. In batch production, everything is cut together and one operation at a time is sewn on all the garments: the time goes into the operation.
Anyone who tries to produce in batches with a made-to-order mindset ends up making twenty garments one at a time and exhausted, without having gained any scale.
The first thing that changes: the sewing pattern
In made-to-order work, you take the customer's measurements and adjust the garment to that body. In batch production that's impossible: you have to produce for a size range, not for one person.
That's why the first change is to stop drafting to measure and move to a graded pattern, with the full size range already worked out. It's what lets you cut fifty garments in seven different sizes without redrawing anything.
The second change: cutting many at once
In batch production you don't cut garment by garment: you spread the fabric in several layers, lay all the patterns arranged together on top, and cut everything at once. A ten-layer spread cuts ten garments in the time it takes to cut one.
That change alone is usually the one that saves the most time in the whole transition, and it doesn't require buying any new machine to get started.
The third change: sewing by operation
Instead of finishing one whole garment, you do the same seam on all fifty: all the shoulders, then all the sleeves, then all the side seams. The machine is threaded just once per operation and your hand picks up the rhythm.
If more than one person is sewing, this also lets you divide the work by operation instead of by garment, which is where productivity truly shows up.
What to decide before you start
- How many styles: few and done well, not many and half-done.
- How many of each size: the middle sizes sell more, so the cut isn't split evenly.
- How much fabric: measured from the pattern's actual fabric consumption, not estimated.
- What gets outsourced: cutting and sewing everything in-house limits your volume sooner than you'd think.
The most expensive mistake in the transition
Cutting the entire run without having sewn a sample. In made-to-order work, you find the mistake with the garment on and fix it right there. In batch production, the mistake is multiplied by the number of garments cut and there is no fixing it anymore.
The sample made up before spreading the fabric is the only defense, and it's cheap: one garment.
Frequently asked questions
- What do I need to go from made-to-order sewing to batch production?
- Graded patterns with the full size range, cutting by spreading instead of garment by garment, and sewing by operation instead of finishing one whole garment before starting the next.
- Do I have to buy new machines to produce in batches?
- Not to start. The change that saves the most time (cutting by spreading and sewing by operation) is done with the same machines. New machines are justified when your volume already needs them.
- How many of each size should I produce for each style?
- The whole range, but not in equal parts: the middle sizes sell quite a bit more than the extremes, so your cutting quantities have to reflect that distribution.
