Jodi, If I were you, I would go to your local library and check out a book with different Cross stitch alphabet designs and borders. I would also check out a book on basic cross stitching. It is really very simple and if you use a larger weave fabric you can easily design your own.
You can probably just browse the internet for Free cross stitch alphabets and then download them. The one suggestion I would make is that when you start stitching, be sure to use the same stitch pattern, meaning go one direction for the first stitch and then the second stitch in the opposite direction, Do it the same each time. sort of like this
///// first then go back and do the cross stitch \\\\\\next Do the same process each time. This will make your stitches look very neat and professional or like you know what your doing. Don't do this / \ \ / do this/ \ / \ / \ not / \ \ / \ / / \ / \ \ /
