Little did I know what I was getting into when I started gathering Corelle pieces and patterns at yard sales. They were all SO PRETTY! Corelle has been around for 35-40 years and have sold over 300 patterns. That's 10 plus patterns per year they have introduced. And they discontinue the patterns regularly. So ebay is a great place to replace those broken pieces. I have found and listed about 200 patterns in 2 years. Some patterns are hard to find, some highly desireable, others are abundant.
