My method is simple and basic, using only the tins and plastic shopping bags.
I start by lining the bottom of the tin with a bag, and then I start layering. For the ornaments that aren't breakable I simple lay them in the tin separating each layer with a plastic bag.
For the ornaments that are more fragile, they get wrapped. I use the plastic shopping bags for these as well.
And again, layered, gently on top of each other. As I said, I have been doing this for years with no casualties!! Easy and inexpensive, especially if you have someone in your family who likes popcorn!! :)
