Hi Jeannie and thanks for your question and pictures of the beautiful spider. It looks like it might come down to the eye placement, as there seem to be two possibilities.
1. An orb weaver, Genus Araneidae, possibly species steatoda, which would include the false and brown widow spiders. These spiders have 8 eyes arranged in two rows of 4 across the face. They make elegant classic webs hanging vertically with the spokes radiating from the center.
2. A cobweb weaver, Genus Theridiidae, of which the Black Widow is one but also the Common House Spider. These spiders also have 8 eyes in two rows of four, but the upper row curves downward and the lower row curves upward. They make a messy three dimensional web with strands running in many different directions.
If the eyes are not a clue, you can also send the picture to Bugguide and see if they can give you a specific identification.
