How To Fix A Hole In Clothing Without Sewing

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.
