It is extra nice to receive a gift when you know someone put time and personal effort in it. So upgrade your gift and make the birthday boy or girl happy with a happy birthday coloring page. Dad will certainly put it on the refrigerator! Our happy birthday coloring pages are a lot of fun. We have them with Happy Birthday in letters which you can use as a card, with birthday cakes and more. Some are easy some a bit more difficult (for adults to use). You will find a nice one, all printable. Use cheerful colors to make it extra festive. We hope you enjoy giving it!
