Learning how to gather knit fabric using elastic is a useful technique that is often used for stretch knit and Lycra fabrics. Gathering with elastic for ruffles and skirts means they maintain their stretch which is important for stretch knit clothing. This method also works well for woven fabrics where you need to create gentle gathers.

How to Gather Knit Fabric
Gathering with elastic is so easy that you may not go back to traditional gathering methods once you have tried this even once!
If you used traditional gathering on a knit fabric skirt, you would find that the seam would not stretch and so it would be hard to get on. Knit garments usually have no zippers, buttons or openings so need to stretch to get over the head.
Using elastic to gather means the waist will stretch for you to get it on and no stitches will pop.
Supplies - Gathering with Elastic
- ¼ inch (6mm) wide clear elastic. (⅜ inch will work too but it is often firmer so doesn’t give the same result.)
Clear elastic is used since it is softer and less bulky than regular woven or braided elastic. If you do need to substitute regular elastic, make sure it is really soft and stretchy.

How to Gather Knit Fabric
Let's start gathering with elastic
Step 1 - Cut Elastic
Cut a piece of elastic to the finished length your fabric will be gathered to. For example, if you are adding a ruffle or skirt to a bodice, you will cut the elastic to the circumference of the bodice.
Stretch your elastic out a few times and double check the length. Cut a little off if necessary.
Step 2 - Divide the Waist
Divide your ruffle or skirt bottom in quarters and mark (This is easily done by folding). Divide your elastic in quarters and mark.
Step 4 - Match the Marks
Match the marks on the elastic to the marks on the fabric. The fabric will gather in between. You can pin the marks together or I find it easier to just stretch as I sew.
Leave a tail of about ¼ inch for you to grab hold of.
Step 5 - Stitch Over the Elastic
Using a zig-zag or straight stitch, secure the first end of the elastic by backstitching a few times.
Important: The elastic needs to be fully within the seam allowance so you don't need to remove or unpick it once you have finished.
Stretching the elastic (not the fabric) between the marks, stitch over the elastic. Leave a ¼ inch (6mm) tail at the end also. Overlap the ends slightly.
Note: You will find that the elastic stretches out just a little when you stitch over it so the slight length adjustment caused by the overlap will not matter.
