How To Fix A Hole In Clothing Without Sewing

Place the patching fabric over the hole.
Lift one edge of the patch and apply fabric adhesive around the hole on the inside of the clothing item.
Carefully press the patch down onto the adhesive. Repeat this step around all edges of the patch.
Secure the Patch:

Place parchment paper or a pressing cloth over the patch to protect it from direct heat.
With the iron set to a medium heat setting (no steam), press down firmly on the patched area for about 10-15 seconds. This helps the adhesive bond securely to both the patch and the clothing.
Let it Dry:

Allow the adhesive to dry completely. Refer to the fabric adhesive’s instructions for drying times, as it can vary.
Check the Bond:

Once dry, gently tug around the patch to ensure it is firmly attached. If necessary, apply more adhesive to any loose edges and repeat the ironing process.
Additional Tips:
For Small Holes: If the hole is very small, you can use a fabric adhesive alone without a patch. Simply apply a small amount of adhesive around the edges of the hole, press the fabric together, and iron as described above.
Iron-on Patches: There are also iron-on patches available that come with adhesive pre-applied. These can be ironed directly onto the fabric, making the process even simpler.
Invisible Mending Tape: Another option is to use invisible mending tape, which can be placed over the hole and ironed to create a discreet and secure bond.
Using fabric adhesive and patches can effectively fix holes in clothing without the need for sewing, ensuring your garments look good as new with minimal effort.
