This humorous patch would make a great addition to a hat, an apron, a vest, or anything you could imagine! Sizes: 3 inches wide by 3 inches tall, 4 x 4, 5 x 5, 6 x 6 I do not sew the hook and loop on it a strong adhesive. This patch is made with 100% Polyester and is a very heavy duty. It is waterproof and very durable. I only use the best material to make my patches they are made with a high-grade twill and the best Madeira thread available I can custom make this bigger or smaller if you like just message me what size you would like All of our patches come with iron on backing. It should last between 30-50 washes. We recommend washing on a cold cycle to keep it in tip-top condition and drying on a low temperature. We also recommend either sewing on or using fabric glue (E6000, for example) to keep the garment permanently secured. Do not apply to leather or nylon as it will not adhere. I recommend sewing or using fabric glue on those fabrics.

Set iron to medium-high heat. Too high of a heat will cause the iron on to not stick. 2. Lay garment on hard surface (not an ironing board). 3. Place patch face up wherever you’d like. 4. Cover with a piece of fabric. You can use cloth or a cotton bandana or just about anything. This is so you do not scorch your patch. 5. Apply firm pressure straight down with heated iron for about 45 seconds. You aren’t ironing out any wrinkles here so keep the pressure constant/firm. 6. Turn the garment inside out and iron the back of the patch for 30 seconds. No need for covering the back side with cloth here. But don’t skip this step! It is important. 7. Gently check if backing is adhered to garment. Let garment cool and enjoy your new patch! Allowing the patch time to cool will help set the heat-n-bond backing onto your garment. If the patch doesn’t appear to be adhered all the way then you can repeat steps 4-6. If for some reason your patch does not adhere at all then sewing or using fabric glue are your other options. Iron on backing can be unpredictable sometimes and not stick. I do not offer refunds for this. But message me with any questions and I will do my best to help.
