After the Main Index template disaster (MITD) things are back up and running at subwayknitter.com, thanks to some help from Gleek. After taking a look under the blogging hood, so to speak, she correctly guessed that the problem stemmed from the display setting.
I had MT set to display the last seven days of posts. Of course, by last Friday night, all the sample posts which I had thrown up there were older than seven days. Their disappearance had nothing to do with the changes I made to my sidebar. Whew!
Never again will I change my templates without first making a backup copy. It's very easy to copy and past an unadulterated copy of a template into a text file. This is exactly what I did. Now, I can tinker with abandon, and if I make a horrible mistake, the backup copy is there.
Meanwhile, my fingerless gloves are working up quickly.
At this rate, I might have a pair by next weekend. I finished the pinky. For a touch of color, I bound off with the same green that I used on the cuff.
