Here's an 80th birthday idea that's memorable and fun: a mailbox stuffed with personalized postcards sending well wishes from your family and friends! Simply customize the postcard text (you can even personalize with a name on the front) and the return address, affix a postcard stamp to the back, and mail one blank postcard to each friend inside an envelope that also contains a little note asking people to please write memories or best wishes onto the blank pre-stamped postcard and drop it in the mail to arrive during the big birthday week. Four postcard colors are available: blue, orange, green and purple. Matching custom stamps are also available to complete the look. See MerrimentDesign Zazzle store for more options. We did this postcard idea for my dad's 80th birthday and he absolutely loved it. You can read the whole 80th birthday postcard story with examples and photos at MerrimentDesign.com.
