I usually make a very small test "quilt" on which I try all kinds of things along the way of my finished quilt. I've found that a good place to try the thread before putting it on the finished quilt, testing the stitch lengths, looking at fabrics together, trying techniques for applique, and on and on. Don't know what I'd do without my little test quilt. You might want to try this method. I do think it would be nice to see ANYTHING Alex can add to our overall knowledge of quilting...thread is a good idea for a topic.
