Reinforce a small hole with a fabric patch
A patch needs to extend beyond the worn area. Covering only the visible hole usually leaves the weak edge carrying the strain.

Examine the cloth around the opening
Hold the material against the light to see how far the fibers have thinned. The patch should attach to sound fabric. A tiny cover may hide the opening while continuing to pull on its weakened border. Trim loose threads only enough to keep them out of the stitching, without unnecessarily enlarging the hole.
Choose patch material with similar stretch and care requirements. A rigid patch on a stretchy surface moves stress toward its perimeter. This straightforward method is best suited to stable woven cloth. Highly elastic garments need a compatible fabric and stitch combination instead.
Decide whether the patch will show
A patch placed on top can be intentionally visible. Cut it with enough allowance to turn its edges inward and press those folds. Rounded corners distribute the shape more gently than sharp points. A backing patch sits on the wrong side, but it still needs to extend well beyond the thin area.
Hold the cloth without tension. Let the garment lie in its natural shape rather than pulling it tightly across a table edge. Baste the patch, then inspect the face for distortion. Only make the permanent join once the repair lies flat.
Support both the border and weakened center
Attach the patch to intact fabric with small hand backstitches or a suitable machine seam. With a backing patch, additional spaced rows can connect the thin center to the support beneath it. Their purpose is to support fibers, not create a rigid, densely perforated spot. Try the stitch density on a scrap first.
Move the repaired area gently as it will move in use. New wrinkles around the border may mean the patch is too small, too stiff, or sewn on under tension. A larger, softer piece can be more useful than adding tighter stitching. Inspect it again after washing. If the surrounding fabric keeps tearing, the material may have weakened more generally, and another tiny repair may offer only a short extension of use.
