When my pal saw these wee sheep he said ,"At last they found a good use for golf tees". I wouldn't go that far but they do make the carving of these ewes and coos a tad easier. Originally they were plain with no message on the ewes. Then I discovered the many ways the word 'ewe' can be exploited. 

Customized messages are available except the obvious one.

Coos are an offspring of ewes minus the message.
