Unless you are doing curves on the outside of your quilt you can do a straight binding, just cut strips from the width of the fabric, that is waht I do even with queen size quilts.
If you are planning on making curves then you would need a bias binding, but I would not think that is a project for a beginner. (It might be easy, but I do not know. Scared to try it myself, but I will, someday!) I LOVE a curved border.
