Fortunately, I kept the *.fla file from last week's lesson, and used that as a starting point. I first selected the text, and got rid of it, so I could use some of this week's techniques. I kept the other parts, but put them on three layers. The triangle shapes with the curved sides are one layer, the two blue "ears" are another, and the central red figure with the stylized A is a third layer. I did this by selecting, cutting, and then pasting in place in the new layer. The lesson in the book prepared me very well for this.
I then decided to work on the text. To have enough room to do something interesting, I decided to expand my canvas a bit. I selected the triangle shape on the left, and moved it down. Then I expanded the two blue "ears" and the central A shape, and used the align function to align them on the top and space them evenly horizontally. That is certainly handy.
Now I had a bigger space to work with. I created some text using Algerian, 72-point, and did a little tweaking of the alignment to get it the way I wanted. The next step was to break apart the text so I could work with it. Then I resized the text to get a larger size than I could achieve when it was still a text object. Then I selected the initial "A" and made it larger still. I cut the text out and placed it on its own layer just in case that proved useful. I then grabbed the gold color used as a fill in the Central A object, and applied it to the text as a highlight. At this point, I realized that I had two shades of blue working here, and that didn't seem to work The darker blue I had in the text worked well with that gold color, so I went back and picked up that color and changed the other blue color to match. While I was at it, I reduced the width of the border on the triangle shapes.
Then I cut out the initial A, and placed it on its own layer for masking. I then used an image of clouds against the sky, and made that the masked layer. I was a little puzzled at first as to why nothing was working here, and then I realized I needed to move the masked layer below the mask layer. That did the trick.
