Seam Allowance Ruler with Magnetic Guide for Sewing Machines

Seam Allowance Ruler with Magnetic Guide for Sewing Machines

Product description

What’s included: one clear plastic seam allowance ruler and a single magnetic seam guide.

Materials and size: the ruler is made from transparent plastic and measures approximately 2 x 2 inches. It includes perforated holes along its length and side graduations for measuring. The magnetic guide is a coated magnet designed to sit against the ruler and hold a fabric edge steady while stitching.

Measurements and markings: the plate is marked with seam allowances ranging from 1/8" to 2" (1/8", 1/4", 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/8", 1-1/4", 1-3/8", 1-1/2", 1-5/8", 1-3/4", 1-7/8", 2"). It also features 15°, 30° and 45° lines for trimming triangles and a 1/4" pivot point for marking binding corners. Side rulers allow measuring other small items.

How to use: slip the clear plate beneath the presser foot and align the chosen hole with the needle position. Lower the needle and foot to hold the plate steady, then place the magnetic guide against the ruler at the desired allowance and lift the plate away. Use the magnet as a fence and feed fabric along its edge to stitch an even seam. The perforations let you register the needle for temporary marks and repeated pieces.

Compatibility: designed to work with most popular quilting and sewing machines, including Janome, Brother, Singer, Husqvarna Viking, Kenmore, Babylock and similar models. The magnet is intended to attach quickly to metal throat plates or nearby metal surfaces.

Reviews

  1. Donna 5/5

    Clear and reliable

    Very pleased — the transparent plate makes lining up easy and the markings are true. I use it to set repeatable marks on my machine for batch sewing.

  2. Scottie girl 5/5

    Convenient kit

    Handy product — compact and very practical for regular sewing tasks.

  3. CM Downing 5/5

    Does the job

    Worked as described and has become a useful part of my sewing space.

  4. wendy 5/5

    Good to have

    A nice little tool to keep by the machine for quick measurements.

  5. healthnut 5/5

    Handy sewing accessory

    Does exactly what it should. Solid quality and helps maintain consistent seam widths while I stitch.

  6. A G 5/5

    Perfect for quilt seams

    Helps achieve even seams across blocks. Easy to operate and the magnetic guide stays put without slipping.

  7. Nicole watt 5/5

    Great for straight stitching

    Makes stitching straight seams much easier. Wish I’d started using one sooner!

  8. tiger65 4/5

    Useful but accuracy concerns

    Convenient ruler, though I worry the large holes could affect exact seam measurements on quilts.

  9. t.schaefers 1/5

    Return — not usable for me

    Retour — für mich unbrauchbar.

  10. CC 5/5

    Saves time on 3/8" seams

    A lifesaver for three-eighths-inch allowances. No more guessing — the process is quick and the magnet stays in place when needed.

  11. Réjane L. 5/5

    Super

    En bon état et livraison rapide. Très apprécié.

  12. Trish C 5/5

    Quick and accurate setup

    This little tool speeds up aligning seams. Far easier than measuring from the needle with a tape measure.

  13. honeyblossomau 3/5

    Disappointed with fit

    The magnet feels very strong and I worry about marring metal surfaces. The hole sizes also make me question needle alignment. Plastic and magnet quality are fine, though.
