Feel free to print as many as you like for personal use or to gift to loved ones. They do look great in a frame or you could resize and make some cute greeting cards.

Please note that the colors may vary from what you see on screen. The final result highly depends on the print quality and choice of paper. I recommend using regular to heavy (150-250 gsm) white cardstock, photo paper or Fine Art Paper.
