What texture gives you the worst ick?

I live soft textures (like who doesn't?) but I cannot STAND holographic material!! Those little Valentine cards I used to get in school where it flashed from one superhero to the next used to make me gag. I would rub my hands on my pants and try to "get the texture off" or "replace the texture."

I had no idea nobody else did that. Everyone else loved them and scratched their nails on them. Just typing that makes my stomach flip! Bleh!

What texture do you hate the most? What texture do you love the most? Mine is polyester!
