1. Cut your 20mm (3/4”) elastic to the length required. Butt the ends together so they sit flush against each other (not overlapped on top of each other) and sew them together using a wide zig zag stitch. Back tack once or twice at the start and finish to ensure a secure finish.
2. With the pants the right side out, lay them on a flat surface and pull the front down so you are looking at the inside of the back waist. Leaving a seam allowance at the top of 1cm (3/8”), lay the elastic waistband down.
3. Holding the elastic in place, turn the top of the band down – the fabric and the elastic. Your waistband should now folded in half with the elastic enclosed inside and a seam allowance of 1cm (3/8”) at the bottom. Pin the waistband in place the whole way around. You’ll know you’ve left enough seam allowance when the elastic loop can move freely inside the casing.
4. Now pinch the front and the back of the waistband together with the elastic secured inside the casing and transfer the pins you just placed so they now go through the back layer also. There will be 3 layers of fabric to pin through.
5. Carefully overlock all the way around the waistband, ensuring to maintain a narrow, steady 6mm (1/4”) seam. If you go too close to the elastic you’ll stitch through it and it will no longer move freely in the waistband. We want it to be able to move and not be sewn down as this will give your pants a nice evenly gathered finish.
Seriously, too easy! You will spend longer reading this blog post than you will overlocking your waistband. True story! Love yas.
