A single-tier seam (synonym - single-tier seam) is a type of seam when connecting clothing parts.
A distinctive feature of this seam is that it connects the parts using one layer of fabric. At the same time, from the wrong side the seam is practically invisible.
Single-layer seams are often used when sewing light clothing - dresses, blouses, skirts. They allow you to maintain the aesthetic appearance of the product without disturbing its silhouette with additional folds and thickening at the seams.
Single-story seams include stitched, stitched and overlay seams. They can be done either by hand or on a sewing machine. The main thing is to select the appropriate threads and needles so that the seam is neat and invisible.
Thus, single-layer seams are a simple and effective way to join clothing parts, allowing you to obtain a neat and aesthetic result. Their use largely determines the appearance and quality of the finished product.
