I did starch, but maybe not heavily enough.....I think the setting squares were cut a little large --- I really don't remember. I worked on this a long time ago and put it away when I realized it wasn't square --- but I love the quilt - the color, the fabrics, the pattern - everything about it, so I decided to get it out and finish it. I can not trim it to be square at this point, but I need to add another border - can I square it after adding that border? It is "off square" by about 1 & 3/4 inches.
