These standard, light weight #2 (what you would find at the fabric store) invisible zippers are on a mesh or knitted tape. YKK calls this a Beulon zipper.
Silky White is a winter white or just off white.
These zippers are the most flexible of invisible zippers. They work well with lace or organza.
When installing this zipper in your garment, use the little plastic foot or just your zipper foot to stitch in the ditch. Watch my videos above to see how I do it.
