Chinese drawstring where one string opens the bag, the other
closes it. Ideas?
I don't know what it's officially called, but I know the bags. It is
a normal drawstring bag, but orthogonal to the normal drawstrings are
another set of strings that are fixed to the side of the bag, sewn to
look like drawstrings but usually with a different colour tassel on
the ends so that you can tell which ones you are looking at. Since
they are attached to the bag and not through the drawstring channel,
when you pull on them, you are pulling the bag open. One set of
strings open the bag, and one set of strings close the bag.
