PFAFF Quilt Ambition 635 Product Review
The Quilt Ambition 635 combines distinctive styling with an impressive repertoire of creative sewing features for quilters, dressmakers and sewers who want to have fun and create on a sophisticated machine.
The legendary Original IDT™ System from PFAFF acts as a built-in walking foot precisely feeding all types of fabric from the top and bottom for perfect stitching every time. It’s a game changer for sewers working with knit fabrics, quilts or dressmakers working with slippery materials like viscose, chiffon, silk or lace.
There is a spacious workspace to the right of the needle that accommodates quilts, curtain panels and bulky garments while the extra high presser foot lift raises the foot to its highest position for thick fabrics. For free-motion quilting or darning, simply drop the feed dog.
Elevate your creativity with a selection of 201 high-quality stitches and sew unique embellishments stitched perfectly up to 7mm. Choose from two sewing alphabets with both uppercase and lowercase letters for easy programming. Creative makers will love the Stitch Creator™ - PFAFF's custom-stitch design function. You can draw your own 9mm stitches directly on the touchscreen or edit built-in patterns to get exactly the look you want, then save them for future projects. Combined with mirror imaging, stitch elongation and the twin needle programme that adjusts width automatically, it gives creative sewers real design flexibility for truly bespoke results.
Practical conveniences run throughout. The automatic thread cutter snips both threads cleanly at the end of a seam, the semi-automatic needle threader handles the fiddly step in seconds, and the speed slider lets you cap the maximum pace anywhere from careful manoeuvring to steady production. Adjustable foot pressure and automatic thread tension cover the move between silk and denim and the LED-illuminated workspace keeps the needle area shadow-free for accurate work.

Materials and Build Quality
PFAFF has been manufacturing precision-engineered sewing machines for 160 years. Recognised for clean and consistent stitches, especially on tricky fabrics like knits or multiple layers, they offer an elevated sewing experience. The jam-proof rotary hook ensures no threads get caught in the bobbin area for fuss-free sewing every time.
Considered features on the 635 include bobbin winding from the needle, immediate tie-off for a quick and easy finish and 29 needle positions for professional-grade top stitching, edge stitching, under stitching, stitch in the ditch and quilting.
The legendary Original IDT™ System from PFAFF acts as a built-in walking foot precisely feeding all types of fabric from the top and bottom for perfect stitching every time. A lever behind the presser foot bar engages a second set of feed teeth. It’s a game changer for sewers working with knit fabrics, quilts or dressmakers working with slippery materials like chiffon, silk or lace.
The freearm extends 200mm (7.87 inches) to the right of the needle, giving plenty of room to manoeuvre larger projects. LED lighting across the sewing area removes shadows around the needle zone, so you can see exactly where fabric is feeding and stitches are forming. The integrated carrying handle makes the machine straightforward to move between a workroom and a class.
The Difference is in the Details
Considered features on the Ambition 635 remove small friction points for an optimal and seamless sewing experience. Sew at up to 800 stitches per minute with a speed slider to adjust the speed for full control. The start/stop button lets you sew without the foot control while the needle up/down stops the needle exactly where you want it which is handy for applique work, tricky corners and detailed topstitching. The automatic tie-off function secures the start and end of a seam so threads stay neat.
PFAFF machines are engineered for lasting performance, with a robust internal design that maintains precision even with regular use. With proper care and servicing, you can rely on consistent, high-quality results for years to come. PFAFF sewing machines come with a 5-year parts and 2-year labour warranty. The Sewing Studio are an authorised service centre for all PFAFF machines.
PFAFF sewing machines are designed for user comfort combining durable technology with artful operation. The bright high resolution LCD screen displays your chosen stitch and sewing settings while the Info Button displays helpful tips and recommendations when needed. Optimized bright lights illuminate the entire work area with less shadows. Choose from 13 languages in the Settings menu to make sure your PFAFF® ambition 635 sewing machine speaks the same language you do.

Inside the PFAFF Quilt Ambition 635
Original IDT™ Integrated Dual Feed
Engaged with a lever behind the presser foot, IDT™ drives fabric from above and below simultaneously. It stays level with the feed dogs to prevent the top layer creeping forward.
Stitch Creator™
Draw original 7mm stitch patterns point by point on the touchscreen, or open a built-in stitch and edit its individual stitches. Finished designs save to the machine's memory.
Automatic Thread Tension
The machine reads the stitch type you've selected and sets thread tension to match, delivering clean formation on both sides of the fabric without manually adjusting the dial.
Speed Slider and Start/Stop Control
A slider caps the maximum sewing pace, separate from the foot control. The start/stop button runs the machine without the pedal, which is useful for free-motion work and chain piecing.
Twin Needle Programme and Mirror Imaging
Enter the twin needle width and the machine restricts stitch width automatically to protect the needles. Mirror imaging flips stitches horizontally or vertically, doubling the design options available from any pattern.

Frequently Asked Questions
What makes the IDT™ System different from a walking foot?
A walking foot clips on when you need it and takes up space around the presser foot. IDT™ is built into the machine, engaged by a small lever, and sits flush with the foot you are already using. That means you get even feeding with any compatible foot, not just a dedicated walking foot, and you do not have to swap hardware mid-project.
Is the 635 a good choice if I'm new to quilting?
Yes, particularly if you want to grow into the craft rather than outgrow the machine in a year. The touchscreen and direct selection keys keep the learning curve manageable, and the IDT™ system removes one of the most common sources of frustration for newer quilters: layers shifting out of line during piecing.
Can I sew heavier fabrics like denim and upholstery weight?
The 635 handles a wide range of fabric weights thanks to the adjustable foot pressure and automatic thread tension. For sustained work on the heaviest upholstery fabrics, a dedicated heavy-duty machine is still the better option, but for denim, canvas tote bags and layered home furnishings, this machine has the control you need.
What is Stitch Creator™ and is it difficult to use?
It is a design tool built into the touchscreen that lets you place individual stitch points to create your own patterns, up to 7mm wide. You do not need any technical knowledge of stitch programming to use it. You draw on screen and the machine handles the mechanics. Designs save to memory so you can reuse them.
How many stitches per minute does the 635 sew at?
The machine runs up to 800 stitches per minute, with the speed slider letting you cap the maximum pace anywhere below that. This matters more in practice than peak speed alone because controlled slower speeds are what you actually need for detailed work, appliqué and precise piecing.
Our standard width fabric can be cut as a Fat Quarter, measuring 50cm x 1/2 the width of the bolt. Above is an example of how your fabric will be received, depending on the quantity ordered.
We also offer a sample service, where you can order 1 single fat quarter of any standard width fabric, to have at home and compare colours. When you are finished, you can send them back to us for a refund (feel free to contact us for more information on this service).
Our fabric can be cut as a Long Quarter, measuring a minimum of 25cm x width of bolt. We will supply the fabric as a continuous length (eg; if you bought 1.25m it will be sent as one piece of fabric).
