Using Thank Yous
It's always nice to thank your audience. Here's a nice set of options for you. Some are more formal than others, and there are a couple with an international flair. The text is not really text: all of the letters can be formatted with fill and line colors and sized to whatever size you like without worrying about changing the font size. If you'd like to format the first letter of every word with another color, no problem. Just select a different line and fill color. If you'd like to bold a word, apply a line color to that word and remove the line colors from all of the other words.
Thank you slides are often the last slide in the presentation. Consider placing the question frameworks in this series on a slide with a title page background rather than a content slide background. The practice of using the title page background for the last page is like putting two covers on a book. It's a nice ending statement. There are a few versions in this series that are too large, maybe, to place on a title page background. Use the content page background in those cases.
Four of the downloads have several options (Thank you for your ...). Just delete those you don't wish to use and format the remaining phrase.
Customizing the Thank You frameworks
Since all of the text in the Thank You series are graphics,. you'll need to group the fields and resize.
PowerPoint 2007 options
There are other nice formatting effects in PowerPoint 2007 that you can apply to the graphic text. Be sure that the effects do not distort the clarity of the, text however. Also be sure that the styles you apply complement the rest of the presentation.
Shadows are particularly nice.
Select color from your document's color palette or a complimentary color so that the graphics will reflect the color scheme of the rest of your document. It's not necessary to use lines with these frameworks unless you want to make the graphic text more bold without sizing it up.
When using the Thank You slides that have text behind the large Thank You, make sure you recolor the background text so that the overlaying, prominent Thank You "pops." The downloads have been developed on a light background, so the background thank yous are light colored. If you are using the thank yous on a dark background, make sure you recolor the background thank yous so they are dark, maybe slightly lighter than your background color. Then choose a color for the overlaying, prominent Thank You so that it is highly contrasted with the background and background thank yous.
3D is a reasonable formatting choice if the depth of the 3D is very small. Sometimes 3D will make graphic text fill in too much and clarity is lost.
Shadows might be a nice formatting choice. Apply the shadows consistently to the page so that the contents appear consistent.
Gradients, patterns, and pictures
Gradients can be used to create depth or interest to the graphic text. Since these slides are simple, you can be a little more flamboyant with your formatting; just be sure these pages are still in line with your style preferences for the rest of the document.
Animations should be selected that will enhance the meaning of the message, not merely to add interest to the slide. With these frameworks, however, you can get a little creative. Pieces come come in from "out of the blue," can grow into existence, etc. In fact, these slides are enhanced by the liberal and creative use of animation. Here is an opportunity to try some different things.
