Janome Jem Platinum 720 Sewing Machine Review: Pros, Cons & Key Features

I’ll be honest—when I first picked up the Janome Jem Platinum 720, I didn’t expect much. It’s only 12 pounds, super compact, and I figured it might feel more like a toy than a real machine. But no, this thing’s legit. I’ve dragged it to sewing classes, set it up on tiny kitchen tables, even tucked it into a carry-on once (don’t ask). It’s ideal if you’re tight on space or just like to move around a lot when you sew.
What I’ve found is that it really suits beginner to mid-level folks—the ones who want simplicity without giving up decent features. There’s a one-step buttonhole (which I wish I’d had earlier in my sewing life), 20 stitches that actually cover most basic projects, and just enough tweakability with stitch length and width.
The automatic needle threader is one of those little things you don’t realize you need until it saves your eyes at midnight. And with the free arm? Hemming sleeves or pant legs gets way easier. For something this portable, it’s sturdier than it looks.

Key Features of Janome Jem Platinum 720
There’s something oddly satisfying about a machine that just gets the way you sew. For me, the Janome Jem Platinum 720 has been one of those machines. What really stood out early on? Speed control. I didn’t realize how much I needed it until I started switching between delicate fabrics and thicker seams. The ability to dial things up or down—like, precisely—makes it feel like I’m not wrestling the machine, but actually working with it.
Then there are the 60 built-in stitches. Now, I don’t use all of them (who does?), but the mix of utility, decorative, and basic stitches gives me room to experiment. The buttonhole options alone have saved me countless hours—especially when I’m finishing up a project and just want that clean, consistent look without fussing around. I can tweak stitch width and length too, which matters more than I thought—especially when matching repeat patterns or seams.
The LED screen? Surprisingly useful. It gives me a quick glance at settings, so I don’t second-guess myself mid-stitch. Pair that with the built-in needle threader and well-placed lighting, and it’s clear someone actually used this machine before designing it. Everything about it feels compact but surprisingly capable.
Advantages of the Janome Jem Platinum 720
I didn’t expect to like the Janome Jem Platinum 720 as much as I do. But after schlepping machines back and forth to sewing class (and cursing every hallway), I started appreciating the lightweight ones more than I ever thought I would. At just 12 pounds, this thing is ridiculously easy to move around. I can toss it in the back seat, carry it in one hand, and still have a free hand for coffee—huge win.
It’s compact, but I’ve found it doesn’t act like a toy. It handles basic sewing with real consistency. I’ve taken it to weekend quilting groups, and I never felt like I was compromising on stitch quality just because I wasn’t on my full-size machine. For travel or small-space sewing setups, it’s kind of perfect.
What surprised me most? How simple it is to use. I’ve tested machines that feel like setting up an old printer—lots of tiny steps, all in the wrong order. This one? I push a button to thread, and boom—done. The automatic needle threader actually works (which I can’t say for every machine with that feature), and there’s a smooth rhythm to using it once you get going. It’s not “beginner-only” either—plenty of seasoned folks I know keep one of these as a backup.
Now, as for stitching: it’s reliable. I’ve used it on cottons, light denim, knits—it behaves well. The 20 built-in stitches cover a lot of ground. You’re not getting hundreds of decorative options here, but honestly, I rarely use more than 10 anyway. Utility stitches, a few stretch, some decorative—more than enough for everyday sewing.
Cons of the Janome Jem Platinum 720
That said, there are things it just doesn’t do. If you’re hoping for embroidery features, or expect a huge stitch catalog, this isn’t your machine. With under 20 stitches, you may run out of creative runway faster than you’d like—especially if you’re into detailed garment work or advanced quilting.
Also, because it’s so light, I’ve found it struggles a bit with thick materials. Trying to layer fleece or canvas? The feed gets fussy, and it feels like I’m fighting it. There’s just not enough weight behind the machine to keep it stable when the going gets tough.
And price-wise… well, this one’s tricky. You’re paying for portability and reliability, sure, but at this range, there are other models—some with more bells and whistles. I love mine, but if I were just starting out again, I might do a little more comparison shopping.
User-Friendly Design and Ease of Use: Janome Jem Platinum
When I first sat down with the Janome Jem Platinum, I wasn’t expecting much beyond the usual entry-level quirks. But I’ll admit—this machine surprised me. It’s one of those rare models where the learning curve feels more like a gentle slope than a wall you have to scale. Everything about the layout just makes sense. If you’ve ever fumbled through clunky manuals or wrestled with bizarre stitch settings, you’ll probably get why that matters.
What stood out to me right away was how intuitive the controls felt. You’re not digging through endless menus or second-guessing which button does what. There’s a rhythm to using it—select a stitch, tweak a dial, and you’re off. I’ve seen seasoned sewists pick it up and fly, but even complete beginners seem to find their footing faster than usual. And that kind of confidence? It builds momentum.
Now, portability isn’t something I used to care much about… until I started carting machines to sewing meetups. The Jem Platinum is light. Like, toss-it-in-your-backseat light. It doesn’t feel flimsy, though—it’s compact without being delicate. I’ve taken it across town and back more times than I can count, and it still hums along like day one.
So yeah, it’s not flashy. But it works. And sometimes, that’s exactly what you need.
Comparing the Janome Jem Platinum 720 to Similar Models
When I first tried the Janome Jem Platinum 720, what struck me wasn’t just the features—it was how compact it felt for everything it offered. You’ve got automatic needle threading, a drop feed, and a surprisingly generous range of decorative stitches. For me, that kind of setup works best when I’m bouncing between quilting and more detailed work. It’s clearly geared toward folks who’ve outgrown the basics and want something nimble but still capable.
Now, compare that to the Janome Magnolia 7330. I’ve recommended that one to a few beginner friends because it’s less about bells and whistles and more about getting the job done without fuss. The controls are simple, the stitches are standard, and honestly, it’s hard to mess up on. If you’re just learning or want something reliable for straightforward sewing, it hits the mark without making things too complicated.
Then there’s the Janome 3128, which I’ve used as a backup machine when I travel. It’s extremely lightweight—almost feels like a toy, but in a good way. No fancy features here, just your core stitches and basic functions. It’s the kind of machine I’d hand to a kid or use for quick fixes when I don’t feel like setting up my main one.
Price-wise, the Jem Platinum 720 sits at the top of this trio—and it shows. More stitches, finer control, more flexibility. The other two lean more budget-friendly, and each serves a purpose depending on what you’re actually sewing.
Is the Janome Jem Platinum 720 Worth It?
Honestly, I didn’t expect much from such a compact sewing machine, but the Janome Jem Platinum 720 surprised me. It’s light—just around 12 pounds—so I can lug it from my sewing corner to the dining table without throwing out my back. That portability alone makes it a go-to for quick mending or travel, but it’s not just a lightweight toy. It actually delivers where it counts.
You get adjustable stitch width and length, which sounds standard, but it matters more than you’d think when you’re bouncing between hemming jeans and piecing together a quilt. The stitch quality is clean—tight, balanced, no skipped weirdness. I’ve used it on everything from curtains to denim patches, and it holds its own better than a few heavier machines I’ve used over the years.
If you’re after something lightweight without sacrificing too much functionality, I think this machine finds a nice middle ground. Sure, if you’re deep into embroidery or need 200+ stitch types, this isn’t your ride. But for regular use? For beginners who want fewer headaches? It earns its spot. I keep reaching for it, and that says a lot.
