Glad it worked out! I've often found it's easier to do borderless printing with HP Photo Creations than other programs.
The matted printing option is fun as well. On the printing screen, set the paper size larger than your original photo, click Advanced Print, and then select one of the presets in the Frame Matte menu. That adds a simulated 3D mat around your photo.
