Stitching elastic can be at times a little tricky, especially when you have to stretch your elastic to the size required; the elastic gathering attachment makes this technique a little easier to handle. Use this accessory for attaching narrow elastic (3.5mm - 6mm) to lingerie, knit or woven fabrics. The holding plate ensures that the elastic is in the correct position while thumb screw adjustments alter the amount of gather to suit your project requirements.
