Excellent photos! They have made me want to grow some little cacti myself. I tried in the past, in my youth. I didn't have the patience and I see now that patience is needed. Now I think I'm ready but I have a big problem, my wife doesn't like cacti.

Mammillaria Bombycina, wow! What a beauty, really photogenic. I'll try to get one at least.

Thanks for showing me their beauty.
