This is son #2 modeling beard #1.
This is son #1 modeling beard #2.
And Shepherd #3. I made his beard a little longer so they didn't all look exactly the same.
Once I made those three, his teacher asked me if I could make one for Moses. I didn't follow the pattern for this, I just cast on a few stitches and increased on each row until I had enough stitches to go around the face. Then I cast off for the mouth and re-cast the stitches on the next row for the mustache.
Here's the whole 3rd/4th grade cast of Moses!
