I love having all the fancy stitches on my machines, and have used many of them for crazy quilt blocks and others. They seem to make a quilt more vintage looking when I use such as crochet threads etc in the bobbin. Of course you have to work from the backside of the block, and need a bobbin casing without the tension screw. I believe one can also use something like silk ribbon this way, though I haven't tried that yet. But one must practice and it's not for everyone.
