I wish I had a big smiley face to paste here. Blogger support came through for me. They pretty much told me that I caused the problem myself by putting two photos side by side. It made the column too wide and pushed the sidebar down to the bottom. It is sure nice to know what to do if that ever happens again. Guess I'll stick to one photo or two thumbnails. Thanks Blogger Support!!! I appreciate the help, and I promise to get better at this.
Now, back to knitting.
