This will ensure that the patch covers the entire tear and provides a sturdy base for the repair. To open the tear, fold the material in half and puncture it from one side to the other. This will cause it to pop open. To securely attach the fabric to the cardboard, it is recommended to use spray adhesive.

Apply the adhesive to the fabric and then carefully press it onto the cardboard surface. It is recommended to perform an adhesive test prior to usage to ensure that it does not penetrate the fabric and cause discoloration.
