Sheep are herd animals so they will come in a mix of ewes, yearling, and lambs along with bases. Each sheep and base is individually cut from 3-ply 1/8 inch Baltic Birch. Just like with real sheep, there may be slight variations from sheep to sheep. Baltic birch is lovely as is, but it can also be stained, painted or coated with shellac. Your sheep will arrive naked ready for you to dress them up.
