Nine photo steps: measure, mark quarters, zigzag, then one straight stitch.","totalDurationSeconds":513,"difficulty":"medium","tools":["sewing machine","fabric scissors","tape measure","sewing pins","fabric marking pen","steam iron","ironing board"],"materials":["knit elastic","all-purpose polyester thread","ballpoint machine needle"],"steps":[{"number":1,"title":"Pre-Stretch the Sewing Elastic Before You Measure It","text":"Pull the length of elastic firmly between your hands a few times. Elastic straight off the roll is stiff, and if you measure it that way the waistband ends up tighter than you meant once it relaxes. Any width from 1/4 inch to 1 1/2 inches works for this method, so pick the one your pattern or your comfort calls for."},{"number":2,"title":"Measure the Elastic Around Your Waist and Cut It 2 Inches Short","text":"Loop the elastic round your waist, snug but not tight. Mark where the end meets the other side of the loop. Go back about 2 inches from that mark and snip. That shorter piece is sized to your body, not to a chart on the pattern envelope, which is why the waistband stays up without digging in."},{"number":3,"title":"Pin the Elastic End Into the Waistband Seam Allowance","text":"Working flat, lay the elastic on the wrong side of the fabric right at the raw top edge. Move the end of the elastic a little into the side seam allowance and pin it. If your garment is already sewn into a tube, overlap the elastic ends and stitch across them several times to make a ring first. That join sits at the back."},{"number":4,"title":"Divide the Elastic and Garment Waist Into Quarters and Match the Marks","text":"Fold the elastic into quarters and mark each fold. Do the same on the garment waist. Pin the elastic to the fabric at each matching quarter and nowhere else. Now stretch the elastic between two pins: the fabric should pull flat with it. If it does not, you need a longer piece of elastic or less ease at the garment waist."},{"number":5,"title":"Set the Sewing Machine to a 2.5 mm Zigzag Stitch","text":"Turn the stitch selector to zigzag and set the width to about 2.5, then nudge it up a touch. Put the elastic under the presser foot and turn the hand wheel toward you until the needle is down in the elastic. A serger works for this pass too, if you have one."},{"number":6,"title":"Zigzag the Elastic to the Raw Fabric Edge While Stretching It","text":"Hold the thread tails behind the foot and grab the elastic halfway to the next pin with your left hand. Stretch it so the fabric lies flat, then sew. The right swing of the needle should land a hair past the edge of the elastic. Stop, reposition your hands, and work round one quarter at a time until you reach the start."},{"number":7,"title":"Fold the Elastic Over So the Fabric Wraps the Waistband Elastic","text":"Take the waistband out from under the foot. It will be gathered on the right side and show the zigzag along the elastic on the wrong side. Fold the elastic down once, exactly on itself, so the fabric wraps it. The elastic is now your seam allowance. If you started with the elastic end in a side seam allowance, keep that allowance free as you fold."},{"number":8,"title":"Straight-Stitch Down the Centre of the Zigzag to Finish the Waistband","text":"Switch back to a straight stitch and lengthen it slightly. Hold the thread tails behind, pull the elastic in front, and stitch right down the middle of the zigzag row. Stretching it while you sew builds ease into the straight stitch, so it will not pop when the waistband stretches over your hips."},{"number":9,"title":"Tug Out Bumps and Steam the Elastic Waistband Back to Size","text":"If a small bump forms near the top edge, give the fabric a firm tug and it will settle. Take the waistband to the ironing board. Hold the iron over it, not on the elastic, and give it a heavy shot of steam. The elastic shrinks back to its normal size and the gathers even out."}],"recipe":null,"lastUpdated":"2026-09-24T15:05:03.466Z","published":"2026-09-24T15:04:56.375Z","license":"CC BY 4.0.
