Not every first machine lives on a desk. Plenty of them live in a closet, come out on the dining table on a Sunday afternoon, and get carried to a class or a friend’s kitchen once a month. That is the job the Singer M3500 is built around, and it is a different job from the one the big gray heavy duty machines do.
The M3500 sits in Singer’s M series, the lightweight mechanical line. It gives you a real stitch menu, a one step buttonhole and a needle threader in a body you can pick up with one hand. There is one design choice in it that beginners should know about before they buy, and it is not on the front of the box.

Quick Answer
Is the Singer M3500 a good first machine?
- Yes, if you need something light enough to carry and store between sessions.
- Singer lists 32 built in stitches, 110 stitch applications, a one step buttonhole and a built in needle threader.
- The bobbin is front loading Class 15, not the drop in style most beginner guides assume.
- Free arm for cuffs and trouser hems, and a metal frame inside a light body.
Bottom line: a lot of machine for the space it takes up. Learn the front loading bobbin properly in the first hour and the rest is easy.
What Singer Lists for the M3500
Singer’s product page puts the M3500 at 32 built in stitches and 110 stitch applications, with a one step buttonhole that sizes itself to your button, a built in automatic needle threader, front loading Class 15 transparent bobbins, a heavy duty metal frame and a removable accessory compartment that exposes the free arm.
The included feet are all purpose, zipper, buttonhole and button sewing, plus a darning plate. That is the standard mechanical set, and it covers ordinary garment and household sewing without further purchases.
What Singer Does Not Publish
There is no weight or sewing speed figure on the product page for this model, so we are not going to invent one. What can be said fairly is that the M series is Singer’s light portable line and the machine is built to be lifted and stored rather than left set up, which is exactly the difference between it and the heavy duty range.
The Front Loading Bobbin Nobody Warns You About
Most beginner advice online assumes a drop in bobbin, where you lift a clear plate on the bed, set the bobbin in, and see the thread supply through the window. The M3500 uses the older arrangement: a bobbin case that loads from the front, behind a small door under the needle. Singer lists Class 15 transparent bobbins for it.
It is not harder, it is just different, and every threading video that shows a drop in bobbin will confuse you. The bobbin goes into a metal case, the thread is drawn under a flat spring on the side of that case, and the case clicks back onto a post inside the machine.
The Two Things That Go Wrong
First, the case is not seated, so it rattles or the machine jams. It clicks. If it did not click, it is not in. Second, the thread was not pulled under the tension spring, which produces a loose loopy mess on the underside of the fabric that looks like a top tension fault and is not one. Our guide to thread nests under the fabric walks the whole check in order.
How It Compares Inside Singer’s Own Lineup
The M3500 makes most sense when you see what it sits between. Singer’s entry model gives you a handful of stitches and a four step buttonhole, and the heavy duty range gives you a much heavier body for thick fabric work. The M3500 takes the convenience features from the top and the weight from the bottom.
| Model | Built in stitches | Buttonhole | Bobbin style |
|---|---|---|---|
| Singer Start 1304 | 6 stitches, 57 applications | Four step | Class 15 |
| Singer M3500 | 32 stitches, 110 applications | One step | Class 15, front loading |
| Singer 4423 | 23 stitches, 97 applications | One step | Class 15, top drop in |
| Singer 9960 | 600 stitches, 13 buttonhole styles | One step, 13 styles | Class 15, top drop in |
Every figure here comes from Singer’s own product pages. Note that the M3500 offers more built in stitches than the much heavier 4423, which is a good reminder that stitch count and capability are separate things.
What It Is Good At
Clothing alterations, curtains, cushion covers, simple garments, school projects and the whole category of jobs that turn up once a week and are done in an hour. The one step buttonhole makes shirt and cushion work realistic, and the free arm makes hemming trousers and taking in cuffs straightforward instead of fiddly.
It also suits small spaces genuinely well. A machine that lifts easily and stores in a cupboard gets used, and a heavy one that has to stay out often does not. If that is your situation, our portable machine guide covers what else to weigh up.
Where It Runs Out
Multiple layers of denim at a folded seam, canvas bag straps and upholstery weight fabric are not this machine’s work. A light body moves when the needle meets resistance, and that is a physics problem rather than a quality problem. When thick fabric is the main job, the heavier frames earn their weight, as our heavy duty guide explains.
What to Buy Alongside It
Two small purchases prevent the two most common early frustrations, and neither is expensive. Both matter more on a light machine than they do on a heavy one.
Spare Bobbins in the Right Class
Front loading machines are fussier about bobbin dimensions than drop in machines, because a bobbin that sits slightly proud in the case drags against the spring. Buy Class 15 bobbins from a known brand rather than a mixed bulk pack, and wind several before you start a project so you are not unloading the case mid seam.
Something to Carry It In
The entire point of a light machine is that it moves, and a bare machine in the back of a car collects dust in the bobbin race and takes knocks on the handwheel. A padded case with a pocket for feet and bobbins keeps the whole kit together. See our machine case guide for the fit check.
Frequently Asked Questions
Does the Singer M3500 have a drop in bobbin? No. Singer lists front loading Class 15 transparent bobbins, which means a bobbin case that loads from the front rather than a clear plate on the bed. Follow the diagram in the manual rather than a video of a different machine, and listen for the click when the case seats.
Is the M3500 the same as the M1500? No. They are both in Singer’s M series, but the M1500 is the simpler model with a much shorter stitch menu, closer to the Start 1304. The M3500 is the 32 stitch model with a one step buttonhole and a needle threader.
Can it sew stretchy knit fabric? Yes, with a ballpoint needle and one of the stretch stitches in the menu. The needle matters more than the stitch: a universal point pierces knit loops instead of sliding between them, which is what causes skipped stitches. Our needle and fabric chart covers it.
Is it heavy duty? No, and it is not sold as such. Singer lists a metal frame inside a light portable body, which is a different design goal. For denim seams and canvas, look at the heavy duty range instead.
Is it a good machine for a class? It is one of the better options, because it is light enough to carry and simple enough that you are not learning a menu system at the same time as learning to sew. Bring your own bobbins already wound.
The Bottom Line
The M3500 is the machine for someone whose sewing space is temporary. It carries the features that matter for garment work, a one step buttonhole and a needle threader, into a body that stores easily, and the only real learning curve is the front loading bobbin case. Get that right in the first hour and the machine gets out of your way. Read next: our beginner machine picks by situation and the Singer lineup explained.
