When saving seeds from peppers I like to bag my blossoms. I don't have the space to really isolate a plant well. Lipton came out with a new product that is perfect. They now have "pyramid" tea bags. You cut one corner off, then use the tea string attached to other corner to tie it off. You get 18 blossom baggers for around $2.50.
