SINGER HD6700C Review: Pros, Cons & Must-Know Tips

👉 Current price & availability: https://amzn.to/3WT5Wh1 SINGER Heavy Duty 6700C Review: real-world pros, cons, and whether this “heavy duty” hero is right for your projects. We put it through denim, canvas, vinyl, and everyday mending to see how it handles speed control, needle up/down, tie-off, drop-in bobbin, and that big stitch library (including block lettering). You’ll hear what owners love — power through multiple layers, beginner-friendly setup, versatile features — and what trips people up — tension quirks, occasional error codes, loud operation, non–backlit screen, hit-or-miss auto threader, and no auto thread cutter. If you’re deciding between a domestic workhorse and a true industrial, this video will help you choose. Example use cases covered: jeans hems, bag-making, patches, light leather, boat seats, quilting cottons, and thick wool. We also talk about calibration, bobbins, and getting the best results on tricky fabrics. Tools and resources: • Printable quick-start checklist (in the full review) • Troubleshooting guide for tension/bird-nesting (in the full review) If this helped, give it a like, subscribe for more sewing gear reviews, and tell me in the comments: what’s the thickest stack you need to sew?
