Heftfaden

Heftfaden is a term used in sewing to describe a temporary stitching method and the thread used for it. It refers to a baste or tacking stitch that holds fabric pieces in place before a permanent seam is sewn.

Use and purpose: Heftfaden is used to position fabric layers, align pattern pieces, secure hems, or hold appliqués and lace in place during construction or fitting. The stitches are intentionally long and loose so they can be removed easily without damaging the fabric.

Technique and placement: Heftfaden is typically applied as running stitches or light tacks. The stitches are usually placed on the wrong side of the fabric to keep them unobtrusive, though in some cases visible basting is used temporarily for alignment checks. The goal is to create enough hold to keep pieces together while adjustments are made, without creating a permanent seam.

Material and color: The thread for a Heftfaden is chosen for ease of removal and may be cotton, polyester, or another suitable sewing thread. It is common to use a color that contrasts with the fabric so that the baste lines are easy to see and remove later, though some tasks prefer a matching color.

Removal: After the final seams are stitched, the Heftfaden is removed by carefully pulling out the stitches or cutting the threads and unraveling them, taking care not to pull loose the final stitching.
