Two‑in‑one tool that holds the flat‑shank machine needle in a D‑shaped seat for safe, square insertion, then threads the eye with a fine wire passer. Especially helpful on low‑light machines or for users with limited dexterity. Speeds needle changes and reduces misalignment that can affect stitch quality. Keep near the presser area for quick access during thread or needle changes. For best results, match the item to your machine or garment hardware and always test on a scrap to confirm fit and finish.
