  • Works as Promised.
I purchased this fabric guide to use when sewing on quilt bindings. I absolutely love it. My layered seams were straight without struggling to control the fabric. The magnet stays in place and easily adjusted for the desired width. Buy it! You will love it.

  • BREXFIRE Upgraded Magnetic Seam
⭐️⭐️⭐️⭐️ A Total Game-Changer for Precision Sewing! I didn’t expect a small tool like the BREXFIRE Upgraded Magnetic Seam Guide to make such a big difference in my sewing, but it absolutely has! As someone who loves sewing but struggled to keep seam allowances perfectly consistent—especially on longer seams—this guide has become one of my favorite go-to accessories. What I love most: ✨ Strong, reliable magnet The magnet is surprisingly powerful. Once it snaps onto my metal throat plate, it stays put. No slipping, no shifting, even when working with heavier fabrics. ✨ Perfectly consistent seams This is where it truly shines. Whether I’m doing a ¼", ½", or wider seam allowance, the BREXFIRE guide lets me keep every line beautifully straight. My quilt pieces and garment seams have never been more uniform. ✨ Smooth edges that won’t snag The upgraded design has rounded, smooth edges that help the fabric glide right along without catching. It feels really well made and thoughtfully designed. ✨ So easy to use No installation needed—just place it where you want your seam allowance, and you’re ready to sew. It takes seconds, and it works with most standard metal sewing machine plates. ✨ Great for beginners and pros alike If you're new to sewing, this tool builds good habits quickly. If you’re experienced, it speeds up your work and helps maintain accuracy effortlessly. ... show more

  • Sewing magnet
Magnet is very strong.

  • Strong magnetic guide
This seam guide is very strongly magnetic. I found it somewhat difficult to move < an 1/8 of an inch to get set exactly at your mark. Once in place it works great

  • NO INSTRUCTIONS, MOVES AROUND
I have a Babylock sewing machine and I was hoping to use this for 1/4" seam allowance as I begin quilting. However, it interferes with the needle when placed on the metal plate (where it magnetizes) and if I move it forward to avoid the needle, it is no longer directly over the metal plate and therefore moves around too much to be accurate. If you have a very wide metal plate, this may work well for you. But it is not useful at all for me unfortunately! :( Also, BEWARE - it does not come with instructions, just an email to contact if you need instructions... ... show more

  • Works decent
Easy to use although you need to use plastic Robbins. The magnet messes with steel bobbins

  • Great for beginners/ strong magnet
Have used this for my sewing projects helps me get a better grip on the items and stay on a straight line as a beginner. The magnet is REALLY strong so atleast you’ll know it won’t fall off unless you want to.
