As You Begin... Some Helpful Hints

1. Save your work often.
(For now, save to the desktop and to your flash drive. When the new computers are all set-up, I'll tell you where you should really save in the future.)
2. Create many different solutions.
You can delete later on, but try several different documents to get some ideas out.
(i.e. You only need 4 final products for this project, but I assume you will make many more in the process.) File - Save as will let you change the same document without ruining your original.
3. Copy layers to make the same thing (your letter) a lot of times.
Layer - Duplicate layer.
