Don't let writing hinder you from sending those nice greeting cards you've purchased to be given out to your love ones. You can purchase a nice stamp and customize it with your return address so it is easier to stamp it on the envelopes. You can even add a signature stamp that you can use inside the greeting card. A great place to find high quality stamps is in rubberstampchamp.com. there are plenty to choose from but a self-inking stamp will be a good choice.
