Adjustable non-separable invisible closure - French blue

A true asset for perfectionist sewists, this French blue invisible zipper combines tradition and innovation with its revolutionary movable stop. This unique feature allows for precise manual length adjustment, eliminating guesswork and guaranteeing a custom result for each creation, whether it's an initial adjustment or a later alteration.

Made from high-quality polyester, it withstands repeated mechanical stress and retains its properties over time. The 23 mm width greatly facilitates handling during sewing, complemented by 2 mm plastic links that ensure completely silent sliding. The French blue, an iconic and timeless color, harmonizes elegantly in classic wardrobes and chic creations.

This zipper comes in three essential lengths: 22 cm short format for delicate finishes, 40 cm universally medium size, 60 cm maximum length for ample and sophisticated pieces.

• Mark temporary points with chalk to visualize the final placement
• Gradually move the movable stop while checking the fit at each step
• Sew with regular stitches at moderate speed for optimal precision
• Trim bias edges to reduce thickness at intersections
• Gently press with a cloth to protect synthetic fibers

Pair this zipper with French blue thread in tone, a flexible ruler, and sharp pins. A variable steam iron will allow you to adjust the temperature according to the nature of your main fabric.
