Your Porcelain quilt is in a recent post named 'Last Year's Quilts'. Use the 'Search' box in the top line above. I need to learn how to do the links, darn it.
I think porcelain refers to the color rather than the pattern. Blue and white like porcelain china.
I have a quilt book of large blocks that has many similar ones. You can get one with that size blocks done in plenty of time.
