'Tis the season

We're planning to get a real Christmas tree this year. We (I!) have lofty plans for us to go to a cut-your-own tree farm and have the whole good, old fashioned, family Christmas (channeling Clark W. Griswold). I realize that my lovely, hand-blown glass ornaments just aren't safe this year, as we'll have a potential toddler in our midst. I have enough non-breakable ornaments to make a decent tree, but I would also like to add some natural (read: edible, if need be) decor as well. I'm thinking popcorn and/or cranberries. How do I go about doing this? Do you use fishing line to string them? All of my crafty readers, please help.
