Yes, I've seen a lot of pics of cross quilts but no patterns.
Just wanted to say that the following one is my favorite.
It's Eugene's version of Storm at Sea from Quilter's Cache.

The Storm at Sea pattern is given at Quilter's Cache.
Perhaps you can figure out how to insert the cross into the pattern.
