Namaste Opal, if you follow the links of BB you get great info. I don one when I go to temple with friends, out of respect for their tradition.
Of the Jews that I know, the more observant ones where one, a matter of pride. At temple they have a basket full for folks to grab as they enter.
I'd like to get a nice one, sort of like if I went bowling often enough, I'd rather have my own shoes...
