Three-piece magnetic seam guide set

The Armilem polygonal seam guide comes as a set of three blue guides built for quilting and general sewing. Each piece uses a magnetic base to hold position on a metal throat plate without tools. The polygonal shape supports edge binding, positioning, anti-curling and crease pressing in one tool. It is suited to beginners, hobbyists and professionals who want repeatable seam allowances.

Magnetic mounting and daily use

The guides attach by magnetic adsorption directly to the needle plate so there is no installation step. If a machine lacks a metal surface behind the presser foot a separate adhesive magnet square is required for the guide to stay in place. In use the fabric slides along the guide edge to maintain a consistent seam width and the guide can be lifted and repositioned instantly for changes in stitching direction.

7-inch polygonal scale for seam allowance

Each guide measures 7 inches and features a polygonal profile with an integrated scale for setting the seam allowance. The single specification that decides fit is the 7-inch length combined with the magnetic base requirement; machines without a ferromagnetic throat plate will need the extra adhesive magnet. Buyers who need a longer straight edge or a non-magnetic clamp system should look elsewhere.

Questions about this item

How does the magnetic seam guide attach to the needle plate of my sewing machine?

The guide uses a built-in magnet that adsorbs directly onto the metal needle plate; no screws or tools are required, just place it where you need the seam allowance.

What physical space does the 7-inch polygonal guide need on the machine bed?

The guide measures 7 inches overall, so it requires a flat metal throat-plate area at least that long to sit securely without overhanging the edge.

What should I do if my machine’s needle plate isn’t magnetic?

The supplier notes that a separate sticky magnet square must be added to the machine surface so the guide’s magnet has something to grip.
