Things You'll Need
Ultra-strong leather glue
Paint brush (optional)
Soft damp cloth
Heavy object or clamp
Bed sheet or pillowcase (optional)
Leather needle and thread (optional)
Although adhesive Velcro strips can be quite durable, they are not typically strong enough to bond to leather permanently. Although you can stick Velcro to leather using glue, not all glues will work. For example, superglue dries hard, so using it increases the chances of your leather stretching or ripping. Instead, you need to use a glue that stays flexible when dry, such as an ultra-strong leather glue.
Cut pieces of Velcro to the desired size.
Mark the exact location where the Velcro will sit on the leather with tailor's chalk.
Apply a thin layer of leather glue to the back of the Velcro, using a paint brush or the applicator that came with the glue.
Wipe away excess glue with a soft, damp cloth.
Apply the pieces of Velcro to the areas marked with tailor's chalk in Step 2.
Apply pressure to the pieces of Velcro on the leather.
Sit a heavy object on top of the Velcro or clamp it and let it sit overnight. Make sure the heavy object or clamp has a smooth surface to avoid damaging the leather. You could also create a barrier between the leather and the heavy object or clamp with a thin bed sheet or a pillowcase.
Remove the heavy object from the leather.
Test out the Velcro. If it is strong enough then you are finished. Otherwise, you may need to sew the Velcro on using a leather needle, also known as a Glover's needle.
