This is an Abecedarian Sentence, written in the Uncial Hand. I did this today while teaching my Online Uncial Class.
"What is an Abecedarian Sentence," you ask? It is a sentence in which every letter of the alphabet is used. It does not have to make any sense at all, but this one kinda does. Anyway, they are good sentences to use while practicing lettering.
The students just learned all of the letters from A-Z, so I was showing them how to put them into words and sentences.
