I would be sure to make it on the larger queen size. These new mattresses are deeper than many of the quilt designers plan. Also, I have started making my queen and king( my marrieds all have King beds) wider not square. They need the extra width wth a body ( or two-three if you count my grand) to be adequately covered.
Great advice! I too have started making them wider than longer. Partly mattress size and partly body size! lol
