I made the invitation by editing one of the ready-made templates on PicMonkey. It took less than 10 minutes, at least half of which was choosing the perfect colors of blue. Here it is, with the personal information removed:
The template I started with is called "Hanukkah Partaaay." It's 6" x 4", which makes it so easy to print invitations inexpenisely. As you can see, I lightened the blue, moved the text, switched out the larger of the two fonts, added a rectangular overlay, added a narwhal, and topped him with a party hat. Quick and easy!
Next week I'll share the decorations, cupcakes, and other narwhal-themed touches from the party. Happy birthday, Trevor!
