Keyword: HOLSTEIN COW HEAD embroidery design
Well, not a holstein exactly, but might do.
Try doing a Google search "embroidery holstein cow pes"
The pes makes sure you don't just get pictures of a cow.
I like this one but it is too small. Thank you
EmbroideryDesigns has several realistic cows. You could just do the head part.
I have 2 different sets of cows and the way they stitch out, it would be almost impossible.
You could also ask Vickie at basketkase to dig. one for you? She does great work.
Country Cow Square at emblibrary could be done without stitching out the frame? Give it a look.
The young lady wants it to be "real".
