It was really beautiful. i am just curious what spider would weave such a web? I have had not a lot of luck on the internet or library...appreciate any info or resources that may help.

Answer 2

"looked liked a sack."

Sac spider (not kidding).

They weave small dome "tents" to hide in, usually in folds of leaves or other small tight crevaces.

Some of them can give painful bites that take a while to heal.
