Attachment Method: This is an iron-on type, so it can be easily attached. Sewing is also possible. Instructions: ① Place the patch where you want to attach it. ② Cover the patch with a pressing cloth. ③ Press the patch with an iron (medium heat) for 20-40 seconds. You can make the adhesion stronger by doing the same on the reverse side. *If you want to attach it securely, we recommend sewing around the edges after ironing.
