Thanks, Alfred, I did miss that question - my apologies. I want to confirm: The Layers panel is normally on the extreme right, right? There was one layer with a triangle on the left side, which when pressed, opened up a bunch of rectangles below the original one that appear to be the ones I tried to draw earlier. Some of these rectangles show a little icon of the line, and some of those are thick and red, so clearly the attributes are attached. But when I click on the layer, the drawing appears on the screen but still as only thin blue lines. It looks like if I click on a layer that has a red, thick line icon, then that line with its attributes should appear on the screen (it doesn't) . Does that help?
