Medium Blue Eyes Patches measures 4x1.7 inches and is Embroidered in Blue. The Small can be sewn on or ironed on to clothing. The Medium Blue Eyes Patches features plastic iron on backing and clean laser cut embroidered borders. You can get very creative with these Blue Eye Patches. Place them on the back of your vest to make it look like you have someone watching your back. Or they work well in the front of your jacket on left and right chests too. You can even place these eyes over the eyes of your existing patch to give it a totally different look. We've tried both the 2 inch and 4 inch size eyes on top of patches and they really add an amazing new look to our existing designs.
