I KNOW what you mean....I have tons of them saved for future use...and by the time I get around to use them there will be tons more.....I narrowed mine down by parks....I made 20 shirts for the trip I just took to WDW....
Be prepared to answer lots of questions about them...we were asked how, who, and where did you get them multiple times a day...the CM'S loved them...I did see a few homemade shirts and I made sure I commented on them...it does take some time to finish them...and of course TIME for the Disigners to make them...Such Talented People...
