Things You'll Need
Instructions
Dress the child in the type of pants you want him to wear with the suspenders. Measure from the top of the waistband at the center back of the pants, over his shoulder to the front waistband at a point halfway between the center front and the side seam. Subtract 4 inches from this measurement and divide it by four.
Cut one piece of 1-inch wide elastic this length and one six times this length.
Sew a medium zigzag stitch along the short ends of the elastic to prevent fraying.
Fold the long piece of elastic in half. Lay it on a flat surface with the fold closest to you. Spread the layers of elastic apart by pulling the top layer to the right and the bottom layer to the left until the elastic forms a "V" shape. Make the angle at the bottom of the "V" a 60-degree angle.
Pin one end of the short piece of elastic over the bottom of the "V" so that the top corners of the short elastic just touch the outside edges of the "V." Move the elastic up and down until you find this point.
Pin the elastic in place with a straight pin through the middle of the elastic. Pin through all three layers to hold the elastic in place.
Turn the stack of elastic over. Set the machine to sew a straight stitch. Sew around the triangle where the top two layers of elastic overlap to hold the stack of elastic together.
Install a zipper foot on the sewing machine. Attach a suspender clasp by folding 1/2 inch of the end of the elastic over the bar at the top of the clasp. Fold the elastic so that the cut end is on the same sauce as the back of the clasp. Stitch 1/4 inch from the fold to hold the clasp in place.
Sew clasps to the other ends of the elastic. Be sure that the same side of all the clasps faces up when the suspenders are laid out on a flat surface.
