Louisiana State University Tigers Embroidered Patch Size is 3.5" Wide x 4.15" High. Available as a sew-on with iron-on and peel-n-stick , and VELCRO Brand backings available. Our iron-on backings include our exclusive Pull-TAB – allowing a clean and complete release its paper backing before ironing. Complete instructions provided for each backing type. Backings: Sew-on Backing is perhaps the best way to adhere patches to any fabric and can be used for any wearable item indoors and out. Completely waterproof and is only subject to the strength of the thread used to sew the patch. This style of backing is permanent. Iron-on Backing is perfect for most light to medium weight fabrics that can withstand pressurized iron heat applied. Not recommended for fabrics that are constantly subjected to water or heavy outdoor use. This backing is permanent depending on use and regularity of washing. Peel-n-Stick Backing is well suited for lighter fabrics and perfect for solid surfaces (wood, metal, etc.). This backing does not require any ironing. It provides a permanent bond to solid surface, but only a semi-permanent fabric backing that may loosen over time (dependent on washing and surface type). Our Self-adhesive Hook/Loop VELCRO Brand backing is the ultimate backing that is removeable. We adhere the first side to the patch and provide the second side (with super-glue like adhesion) for you to secure to whatever medium you wish. This backing is perfect for any fabric, is waterproof, washable, and will withstand almost any type of environment.
