Singer 7640 Confidence Sewing Machine Review
The Singer Confidence 7640 is a modern computerized sewing machine designed with a clear focus on ease of use and versatility. Whether you’re learning the ropes or want a machine that keeps up with a wide range of projects, the 7640 brings a lot to the table. It blends Singer’s long-standing reliability with user-friendly features aimed at making sewing more approachable and efficient.
With 379 stitch applications, a programmable needle, speed control, and features like a one-step buttonhole and top drop-in bobbin, it’s built to support everything from simple garment work to more decorative or personalized sewing. While not without its limitations, especially for heavy-duty or highly detailed work, the 7640 strikes a good balance for most home sewers.
Features and Functions on the Singer Confidence 7640

For a mid-range machine, the 7640 is surprisingly feature-rich. You’ll find adjustable stitch width and length, speed control, and a top-loading bobbin system that makes setup straightforward. The LCD screen is easy to read, and navigating between stitch options doesn’t feel overwhelming.
It’s well-suited to daily sewing tasks, whether that’s mending, dressmaking, or piecing quilts. However, if you plan to regularly work with thick fabrics or intricate embroidery, you may notice it doesn’t always perform with the same precision under pressure. Still, for general sewing and creative flexibility, it holds its own.
Stitch Applications and Variety

One of the standout features is the range of 379 stitch applications. That includes basic utility stitches, decorative options, and specialty stitches for quilting and stretch fabrics. It’s a generous selection that opens the door for experimentation, whether you’re embellishing a hem or piecing a more decorative project.
In regular use, the stitches are neat and consistent, especially on standard fabrics. With thicker layers or bulky seams, however, the quality can occasionally dip, so it may not be the best choice for heavy-duty materials.
Ease of Use
Several features on the 7640 make it especially welcoming to newer users. The one-step buttonhole is intuitive, with eight styles to choose from, and the programmable needle up/down function is handy for tasks like quilting or pivoting corners.
The top drop-in bobbin is another practical inclusion – it’s easy to thread and lets you keep an eye on the remaining thread. Overall, these additions help reduce the learning curve while improving accuracy and convenience across different sewing types.
Customisation and Control
Personalizing your stitch settings is easy thanks to the adjustable stitch width and length, both clearly displayed on the LCD screen. This is especially helpful when switching between fabric types or project styles.
The built-in speed control is also a plus, letting you slow down for tricky curves or speed up when doing long straight seams. It’s a simple addition, but it can make a big difference in terms of precision and comfort while sewing.

Stitches and Buttonholes
The machine comes with 200 built-in stitches, which include practical, stretch, and decorative stitches. You also get a one-step buttonhole that automatically measures and creates uniform buttonholes every time – no manual measuring or guesswork required.
This setup works well for both garment sewing and home décor projects, though it doesn’t have the stitch library or customization capabilities of more advanced (and expensive) models.
Built-In Lettering
Built-in lettering gives you the ability to personalize items with names, labels, or monograms. It’s a fun feature if you like to add a signature touch to your sewing. That said, it’s fairly basic – great for simple embellishment but not a replacement for true embroidery functions.
If your focus is on detailed monogramming or decorative fonts, you may find the options here limited.
