When I did "Storm at Sea," I made it as a class project using Marti Michell's templates: Sea Diamond Set #8605 and Template Set B #8252 (12" blocks). While I found her directions a little confusing at first, the teacher guided me through, and everything just seemed to "click" all at once. The finished quilt had a red heart in the lower right corner; the rest of the quilt I made in dark blue and mottled grey. I thought it turned out very well.
I am planning on doing another one using floral fabrics to do a "Glorious Garden" pattern I found on the internet. Using the templates makes cutting and matching corners easy for me.
