Our squadron patches are 100% embroidered with velcro backing, we also offer twill fabric with embroidery to give a dimensional effect. Another patch option is PVC leather-like with a black merrowed border. We also make 100% PVC patches with excellent detail. The PVC patches are big in Europe and they are gaining popularity in the USAF. One more patch option to think about is embroidery combined with sublimation dye to achieve something that 100% embroidery cannot. This is an excellent option for that one crazy graphic that has too much detail for thread to handle and you want the patch to look awesome, this process is for you.
