Supplies you'll need
- Stretchrite 3/4-Inch White Buttonhole Knit Elastic (you can buy this by the 30 yard spool on Amazon, or purchase by the yard from my River Stitch Fabric & notions shop on Etsy.
- Fusible Interfacing suitable for fabric - I use Pellon 931TD Fusible Midweight
- 2 buttons
- safety pin
- sewing machine
Attach interfacing to the wrong side of the waistband.
Mark the center of the waistband, and then measure 4" to both sides of center and mark. These markings are where you'll make your buttonholes for the elastic openings.
This spacing works well for size 4T. You should check this measurement on your child to note where you want the buttons to sit. I don't like them to sit on my daughters hips, that would be uncomfortable for her. I like the elastic to come around her hips to the front - it gives plenty of room for the elastic to stretch and doesn't bunch odd in the back of the pants. If you're confused, please ask questions.
Step 3:Fold and press the waistband in half widthwise, then mark the position of your buttonholes. Start buttonhole 3/8" down from center fold. Sew a 7/8" buttonhole (slightly larger than your elastic).
Using a seam ripper, carefully open your buttonhole.
On the waistband edge that does not have the buttonholes, fold under 1/4" seam allowance and press (as shown). This will come in handy when you edge stitch the waistband later on - trust me on this.
Fold the waistband, right sides together. Sew, with the appropriate seam allowance. Turn the waistband right side out and press seam open.
Step 7:With the right side of the pants up, pin the right side of the waistband to the wrong side of the pants, matching the center back of the waistband to the center back of the pants. Make sure the buttonhole side of the waistband is on top (as shown below).
Step 8:From the right side of the pants, sew the pinned waistband to the pants, with the required seam allowance.
Press the waistband up, and fold it on the fold line toward the pants right side.
Fold the free raw edge of the waistband under 1/4" and pin this edge to the pants front and topstitch through all layers to secure it.
Edgestitch along the top fold line of the waistand.
Sew buttons on waistband in front of the buttonhole openings (as shown).
Cut a length of elastic that will run from one buttonhole to the other. Mine is 18", add 1" for seam allowance.
Fold elastic ends under twice, and sew to secure.
Using a safety pin attached to one end of the elastic, insert the elastic through one of the buttonhole openings in the waistband and out of the other opening.
My latest trick.... after many many sewn waistbands...to keep the elastic from turning inside the waistband casing, stitch a line along the center back seam to secure the elastic in place. The elastic will still stretch from either side, but this will keep the elastic from pulling out of the pants or turning.
And you're done!
