If you will be reusing the button, be sure to keep it on hand.
Going with simple solid color that is close to the fabric is sufficient. It does not have to be a perfect match.
The marks belong on both sides of the fabric, where the button will sit. You can also stitch an ‘X’ in the spot where the button will be if you feel confident about your sewing abilities.
Pant fabric is often thick and sturdy. Be careful not to puncture your skin, as you may have to use a great deal of force to break through the fabric. You can use a thimble on your thumb to keep the needle from hurting you.
You can repeat this process as many times as needed to make the button feel secure. Trim the thread directly above the knot to avoid undoing the knot by accident.
Stitch in the same direction 4 to 5 times before switching to the other diagonal pair of holes. If there are other buttons that use a stitch that looks like two letter ‘I’s next to one another, called “II” stitches, you can stitch them to match by not crossing over to the diagonal hole when making the stitch. Instead, stitch through the hole straight across.
The spacer should not block the button holes, but keep the button’s edge sitting above the fabric.
Cut the fabric in the same way as with a 2-hole button.
