What is a open seam

Answer 1

An open seam is a sewing term that refers to a gap or hole in a seam that should be fully stitched closed. It occurs when the stitching of two pieces of fabric is not continuous or when the stitching is not secure, allowing the fabric to pull apart at the seam. Open seams can weaken the overall structure of a garment or item and should be repaired or reinforced to prevent further damage.
