Hemline Shirring Elastic - White - 0.75mm x 20m

Use a universal needle or a ballpoint needle, depending on the fabric.

Yes, but ensure your serger is set up correctly for elastic applications.

Measure the area you want to shirr and subtract the desired finished length. Then, cut the elastic to about ⅔ to ¾ of the measured length.

A zigzag stitch or an elastic stitch is recommended for secure attachment and stretchability.

It is best to avoid ironing directly on the elastic. If necessary, use a low heat setting and a pressing cloth.

Store the elastic in a cool, dry place away from direct sunlight.

Make sure your stitches are secure and the elastic has not been overstretched during sewing. If it is still stretching, consider using a different elastic type or brand.

Reduce the tension on your sewing machine or use a finer needle. Ensure the elastic isn't being stretched excessively during sewing.

Ensure that the elastic is stretched evenly as you sew. Use pins to secure the elastic to the fabric at regular intervals.

Work in small sections and avoid pulling the elastic too quickly. Use a slower sewing speed if necessary.
