I had the urge to make a gray-tabby-like tail out of my ample scraps a while back, and gave it full silver guard hairs. It's thin wide, and about 24 inches in length.

The guard hairs are attached slightly differently than usual, with something I had tried in the past with success, and cannot be pulled out purposefully unless you are really trying to damage the tail. So that's cool, they're more permanent, but they do result in some under-hardness. The tail is only superficially soft. Although, yarn tails have bony cores naturally anyway.

This tail is for sale for $60 ($20 off the original price!), including shipping and a brush within the US. So please let me know if you are interested. Otherwise, just enjoy pics! : D
