If you break or lose the buckles from your bib overalls, or if you are making a pair of bibs and need buckles, use Dritz overall buckles to keep your overalls from falling down. Dritz overall buckles come with no-sew jeans buttons, so if you need to add buttons you get to use a hammer instead of a sewing needle. Buckles are sold according to strap width, so you also need to know the width of your straps in order to get the right buckles.
Find the thick, folded end of the overall straps. You should see stitches running through the thick, folded fabric.
Cut every other stitch in the thick, folded fabric at the ends of the straps. Unfold the ends. Use your fingertips to grab and pick out the loose threads.
Slide the old buckles off of the straps. The buckles should come off easily after the thick fabric has been unfolded.
Look at both sides of the buckles. One side will have a slight inward curve while the other bubbles slightly outward. The slight outward bubble is the front, or face, of the buckle. Place the buckle or buckles face down on the table, with the skinny end pointed away from you.
Place the overalls bib side up on the table with the straps pointed at the wide end of the buckles, making sure the straps are flat.
Tip the buckle by lifting up the skinny end. Slide the strap's end through the buckle's bottom flat gap, so the strap sticks out the front of the buckle.
Skip the second, or next, flat gap, and feed the strap through the buckle's top flat gap. Pull at least 4 inches of strap through the buckle.
Fold the strap down and feed it into the buckle's flat centre gap, the one you skipped when you fed the strap through the first gaps. You might have to loosen the strap on the front of the buckle to complete this step.
Feed the strap around the buckle's bottom bar, so it rests between the strap's front and the buckle's bottom bar. Pull out at least 3 inches of strap so you have room to sew the strap ends.
Make a 1/2-inch fold in the strap end, then fold the end a second time so the strap ends are completely folded in. Sew across the fold, with the machine set to make a long, straight stitch.
You can also use overall buckles to hold decorative straps or fasten straps on carrying cases and bags.
