A slender piece of Basswood will do the trick.
With a minimal amount of band saw work the piece was ready for carving.
I planned to carve the tail as well.
At this point I just happened to be talking to my brother-in-law and sister-in-law, Bill and Angela about using either doll hair or something similar. They suggested why not use real horse hair!
That was perfect! They contacted their longtime friend, Rachel in North Carolina and a couple days later I received an envelope with a hunk of horse hair in it.
I'd like to thank Bill and Angela for the idea and Rachel for "sacrificing" her horse's tail.
Now, the carving took on a whole new meaning.
I removed the wooden tail, whipped the end of a gathering of horse hair and glued them together.
The results made all the difference.
The "Horse's ..." recipient is a horse lover and rider and she loved the results.
And that's the end of this tale!
