Cow Skull Planter with Moss

This photo of an awesome planted arrangement in a cow skull from Seed to Stem is extremely timely for me.

As I reside in Texas, my sister (in San Francisco) sees me as her source for all sorts of western themed paraphernalia.  She recently requested that I locate and mail to her a cow skull, with horns if possible.  Suffice to say this was a goose chase as the cow skulls with horns are pretty expensive - and large!  It was going to cost a fortune to mail her one.  Long story short, we found a decent hornless skull at a roadside sale in a podunk town in Texas (which looked a lot like the one in the photo) and were able to mail it to her.  What will she do with this skull?  I do not know.  Maybe make a moss planter out of it.
