AllStitch offers Blank Patches/Emblems for commercial/home embroidery. Each blank patch is a white poly/cotton twill and comes with an overlocked merrowed border. Our colorfast threads are designed to withstand the harshest of washing processes. AllStitch Embroidery supplies also offers sheets of blank patch material with unfinished edges. Use this patch fabric to make your own custom shapes and sizes of embroidered patches. All blank patches are sew in patches. If you would like to have heat seal on the back, purchase Fuse-n-Bond heat seal patch film for the back. This can be applied after you have embroidered the patch and will turn it into an iron on. (These Patches Are Not Suitable For Sublimation)
