Staceymerrill, very, very creative!
My only suggestion would be to add the dates and resort of the WDW portion, the cruise dates, the name of the ship and itinerary, and the names of all the family members
You could do that centered on the back in a list, with maybe a couple of small characters, one at the top and one at the bottom. If you put your WDW info first, pick a clipart that would depict one of the characters at the park; for the
DCL part, I am sure you can find pictures of Mickey as the captain online.
If you download the Disney font (there has been lots of talk about that lately), all of your script would be cute. There was also a post today about a font that looks like the cruiseline font -
You could have a lot of fun playing around with this!!
Post a picture if you can of your work in progress - we would be glad to offer suggestions!!
If you have little ones that you have to keep up with, some neon color would be the easiest to see, like the neon green, but it all depends on how your clipart prints on the shirts (whether you need to have the white in the background).
Oh, I wish my DH would wear one..........!
