These aren't standard league patches -- perhaps they should be in the "miscellaneous" section.  They're patches of each skater's name and number attached to the back of their jersey.   From the looks of it I don't think the stitching was directly embroidered onto the jersey -- let me know if I'm wrong, Charm folks, and I'll remove this (since embroidery directly on a garment isn't a patch).  Either way, they're neat looking.
