Not sure this is what you want, but it would be relatively easy to have labels made that you then attach to the fleece. Much easier to ship, less expensive than shipping the blankets back and forth, and no fear of a blanket being lost in shipment. There is someone on the QB who does labels for quilters who want to order them. I don't have the member name, but someone else who reads this might know who it is.
Edit: Also, Google EmbroiderMe to see if there is one in your area. I know they do hats, etc. They might be able to embroider right on your blankets. I think they're pricey, though.
