What kinds of bags do you use?

[Hilde]

I plan to bag my tomatoes next year to get pure seeds, and I wonder what kinds of bags you use when you do it?

What materials and how big are the bags? Do you have pictures? When do you put the bag on and can you reuse it, or do you have to clean it before reusing it?

I guess I could hand pollinate, but I don't know the difference between a male and a female flower!

A lot of questions, and if they have been asked before, I apologize.
