Mea12: 18" wide, 4" long, 12 inch blocks? Hmmmmm. Not following you on these dimensions. Confusing.and not adding up.
i would applique the soup bowl and steam logo. Minimal words...just the name of the event. Frankly, the thought is there but if it is going to hang in a public space, not sure that I would put a lot of effort into this. It just might "walk". I WOULD make one to give to the person who heads this event for their peronal home memento. Just my 2 cents. Things have a way of disappearing in a public space. Not trying to be negative...just cautious.
