Happy 90th Birthday Milestone Postcards - in Blue

Here's an 90th birthday idea that's memorable and fun: a mailbox stuffed with personalised postcards sending well wishes from your family and friends! Simply customise the postcard text (you can even personalise 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 colours are available: blue, orange, green and purple. Matching custom stamps are also available to complete the look. We did this postcard idea for my dad's 80th birthday and he absolutely loved it.
