- Take your elastic to measure your waist size
- Find the ideal length to obtain a waist that is neither too loose (the skirt should fit snugly around your waist) nor too tight (you should remain comfortable).
- Use a pin/safety pin to mark this location: the remaining margin will allow us to sew the 2 ends of the elastic together
- Take your second safety pin and pin it to the other end of your elastic.
🧷 Tip: This pin will simply serve as a guide to tuck all the elastic into our waistband. This is a very common sewing tip that we already showed you with our 90s scrunchies.
- Slide this end inside your "tunnel" and slide the safety pin through until it comes out the other side. Throughout this process, be sure to keep the elastic flat inside, and also be careful not to lose the other end inside the tunnel.
- Once you have gone around the waistband, bring the two ends of the elastic together at the mark we marked with the first safety pin earlier and pin them together.
- Using a straight stitch, sew a large "crossed out" square to assemble and secure. If you wish, do not hesitate to make more back and forth stitches to obtain a solid seam. Do not forget the backstitching as usual and cut the excess threads.
To sew your barred square, nothing could be simpler: follow the different steps indicated on the diagram below, playing each time with your presser foot for the angles (leave the needle in place, pivot, lower the foot), as we saw above:

- Finally, pull at the waist to make the elastic disappear inside
- All that's left is to topstitch the ribbing to close the opening we left, and that's it. Once again, we make our backstitching stitches at the beginning and end of our stitching and we cut the excess threads.
