Two sources come to mind. Bonnie Hunter (
https://quiltville.blogspot.com/p/free-patterns.htm) has many free patterns and online tutorials that use 2 inch cuts. Wedding Dress Blue (
https://weddingdressblue.wordpress.com/) also has a collection of free patterns and tutorials that make use of 2 inch squares. One that I am working on currently is called Growing Up Odd. I have converted it to 2.5 inch squares and have made it previously. Happy searching.
