Presser feet explained

Every sewing machine has feed dogs — the little serrated bars that rise through the needle plate and pull the fabric backwards a stitch at a time. They only touch the bottom layer. When you sew two layers together, the bottom one is being actively pulled and the top one is being dragged along by friction, so the top layer travels a fraction less far on every stitch. Over a two-foot seam that fraction adds up to an inch, and that inch is why the ends do not line up.

A walking foot is a second set of feed dogs mounted in the presser foot, driven off the needle bar so they move in time with the ones underneath. Both layers get gripped and both travel the same distance. That is the entire idea, and it is why it fixes quilt sandwiches, wavy knit hems and plaids that refuse to match.

Where it matters most is quilting, because a quilt is three layers with a compressible one in the middle. Without a walking foot, batting compresses unevenly under the foot and squirts forward, and you finish a quilting line with a fold pushed up ahead of the needle.

Two buying notes. First, shank type: home machines are mostly low-shank, but not all, and a walking foot for the wrong shank will not sit at the right height. Your manual says which yours is. Second, this is the one accessory where the machine manufacturer's own version is usually worth the premium — a walking foot has moving parts, and a cheap one develops play that shows up as an uneven stitch.

Brother includes a walking foot with the CS7000X. It does not include one with the XM2701, the LX3817 or the XR9550, and Singer does not list one with the M1500 or the Heavy Duty 4423. If you are comparing prices between machines, this is the accessory that changes the arithmetic.

Almost every quilting pattern ever written assumes a quarter-inch seam allowance. That is not a style choice, it is a unit: block sizes, sashing widths and final quilt dimensions are all calculated from it. Sew at five-sixteenths instead and every block finishes small, and the error compounds with every seam.

A quarter-inch foot solves it by geometry. The foot is manufactured so that its right-hand edge, or a small metal flange on it, sits exactly a quarter inch from the needle. You align the raw edge of the fabric with that edge and stop thinking about it. Accuracy becomes a matter of feeding straight rather than of judging distance.

There is a free alternative on some machines. Brother lists a needle position key on the XR9550: instead of moving the guide to the needle, you move the needle relative to the standard foot edge, then measure once and note the setting. It takes five minutes to calibrate and costs nothing. Machines without that key — the XM2701, the LX3817, the M1500 — need the foot.

Brother includes a 1/4 in foot with the CS7000X. None of the other machines on this site includes one. If quilting is why you are buying a machine, that is worth about the price of two feet in the comparison.

The CS7000X is the machine we point a first-time buyer at, and the reason has nothing to do with its stitch count. It is the presser feet. Brother lists ten of them in the box — zigzag, buttonhole, zipper, button sewing, overcasting, blind stitch, monogramming, quarter-inch, quilting and walking — plus a quilt guide. Two of those, the walking foot and the quarter-inch foot, are the exact accessories a beginner ends up ordering three months in, and they are not cheap bought separately.

The second reason is the threading. Brother's published specification lists an automatic needle threading system and a quick-set drop-in top bobbin. Threading the needle and setting the bobbin are the two jobs that make people put a machine back in its box, and this one turns both into a lever pull and a drop. On a front-loading machine you are removing a case, seating a bobbin in a particular orientation, and hoping.

It is a computerized machine, which means stitch selection is a mode key and a shift key against an LCD rather than a dial. That is a genuine trade-off, not a straight upgrade: a dial is legible at a glance and has nothing to fail, while an LCD tells you the stitch width and length the machine has actually selected. For someone learning, seeing the numbers is worth more than the simplicity of a dial.

The extras matter more than they sound. The detachable wide table turns a small free-arm machine into something you can push a quilt across, and the hard protective cover is the difference between a machine that stays out on a table and one that lives in a cupboard collecting dust. Brother also publishes a 25-year limited warranty and free phone and online technical support for the life of the product.

We have not sewn on this machine. Everything above is from Brother's own specification page, and the price on the button is live from Amazon rather than anything we typed. What we can tell you is what the box contains and what that saves you buying — which, for a first machine, is most of the decision.

The kit it pairs with: It already includes the walking foot and quilting foot, so its starter kit is short: needles, bobbins, thread, shears and pins.

Every roundup on this site carries one pick we tell you not to buy. This is it, and it is here because it is the most commonly bought wrong thing in the category — the reflex purchase a new owner makes on the same order as the machine.

Start with what is already in your box, because the manufacturers publish it. Brother lists the CS7000X carton as containing ten sewing feet, a quilt guide, an accessory pouch with a needle set, a ball point needle, a twin needle, a spool pin, three bobbins, a cleaning brush, a seam ripper, a screwdriver, an eyelet punch, an L driver, the operation manual, a hard protective cover and a wide table. The XM2701 ships with a darning plate, an accessory bag with a needle pack, a twin needle, a screwdriver, an extra spool pin, three bobbins and the power cord. Singer lists the M1500's included accessories as an all-purpose foot, a zipper foot, a buttonhole foot, a darning plate, a pack of needles, Class 15 bobbins, a needle plate, a screwdriver, spool pin felt and a seam ripper / lint brush.

Now compare that to a 100-piece kit's contents list. Needles, bobbins, a seam ripper, a screwdriver, a brush, spool pins, a threader, a tape measure. You own all of it. What you are paying for is duplicates, and duplicates of the cheapest items in the category.

Worse, the two categories where a generic kit could add value are the two where fit is not guaranteed. Bobbins have a class — Singer specifies Class 15 transparent for both of its machines here and recommends its own or INSPIRA-branded bobbins for best results. A bobbin of the wrong class or the wrong material seats badly and produces the loops-under-the-fabric problem that sends people looking for a repair shop. Presser feet have a shank type, low or high, and a foot for the wrong shank sits at the wrong height.

The genuinely useful spend, for the same money or less, is short and specific: a walking foot if you will quilt, a quarter-inch foot if you will piece, a second pack of universal needles, a handful of the correct bobbins for your machine, and a cover if your machine did not come with one. That is what our starter-kit roundup is made of, and there is a reason none of it comes in a hundred-piece bag.
