New ties available on Zazzle. These use patterns I made for Spoonflower but aren't available from there yet.
Fossils, including trilobites, ammonites, and turritellas. I was asked for a less brightly colored version of my older Fossil Layers design.
Tie covered with bacteriophage viruses rendered to look like an electron microscope image colored in shades of blue to resemble porcelain. I can't claim to be a fan of viruses in general, but if I had to pick a favorite it would definitely be the bacteriophage. Not only do the infect bacteria (rather than us) but they're the coolest looking virus out there.
Similar to the last tie but these are Rhinoviruses. You know, the virus most commonly associated with the common cold. Now if you get sick and accidentally wipe your runny nose on your tie it will just add realism.
