Storm At Sea can be done
I've made one and am tieing the second one. The 1970's book I got the pattern from calls it challenging, and it is . Mainly because there are so many pieces. But everything starts with rectangles and squares.
The worse part I feel is the constant pressing needed to block the rectangles and blocks. And I am still not good with corners, but on this second one the motion of the patterns is true. If you want something to zone out with this is a good project. I'll try to show you a section, because it's a huge king quilt .
