I've received this Goupon over for personalized photo blanket for $59. It measures 71" by 53". I supply up to 4 photos to be on the blanket. I expected this to be something screen printed on an already woven blanket, but according to this: the image is woven in. Is the technology available to do this so cheap? I'm really looking at this with some skepticism. I haven't included a link because I'm not sure if forum rules allow it.
