Part of the confusion may be because in some versions, Corn and Beans is actually the same as Northwind (though not on Quilters Cache).
This is Corn and Beans
This is Northwind, repeated and rotated
And this is Ocean Waves
Clear as mud, right? I'm in the northeast and I think maybe that's one reason I know the block as Northwind and not Corn and Beans. We call corn and beans succotash up here! :D
