As I was reading the paragraph where NagFa reply with “new concepts, longer phrases…” I couldn’t help but go through my list of Ambigram Greeting Card titles to find the longest phrases I have drawn. Some of them (each is rotational) are listed here:

I Am Nuts Over You! – 5 words, 14 letters (and 1 exclamation point)
You Are My Shining Star – 5 words, 19 letters
You Are Cute As A Bug – 6 words, 16 letters
Thank You For Being My Friend! – 6 words, 24 letters (and 1 exclamation point)
A Touch Of Sunshine For You!!! – 6 words, 22 letters (and 3 exclamation points)
Happy Anniversary, Mom and Dad – 5 words, 25 letters

“Happy Anniversary, Mom and Dad” inverts to “Mom and Dad, Happy Anniversary.” It was the first Ambigram Greeting Card I ever made, and it has more letters than any other card in my entire collection! … to date, that is…

I am constantly sketching possible phrases, so we’ll see what other “ambigram greetings” come along.
