Can anyone help me with identifying which spider makes these webs...they are very cobwebby (not symmetrical like an orb weaver's web) and they are VERTICAL?! There are hundreds of them this morning along the hedgerow in front of our woods. Generally they are all about 2 to 6 feet above ground and they are suspended between leafage or twiggy branches by leader lines (for lack of a better description). They remind me of irregularly shaped cobweb hammocks :>]]

Any suggestions? Thanks for your time!
