Well I certainly have changed my tune! My first thought of a tune turned into a problem very quickly --- idea might take too much time to work out. Plus I don't know that people are familiar with it anymore...so now I have another one going.
(I did a late posting for paris1889's december card, on last month's thread, so go check it out, too -- it's lovely. My computer cord is still MIA so created a bit of a hurdle to post.)
