Icicle Ornaments From Plastic Bottles

Based on Icicle Ornaments From Plastic Bottles by n k.
Thanks n k for the great tutorial and idea! I made mine from a 2L bottle. After some trial-and-error, I found that they turned out better if I made them as thin as possible. I varied thickness in some (very thin in parts of it and thicker in other areas), which resulted in a pleasing outcome. At least I think so! :)
