How cool would it be to get custom t-shirts made up for these types of events-  Maybe planning some kind of family reunion/trip to Disney...maybe you could get custom shirts for everyone going.  Are you organizing a softball team or a bowling team and need shirts?  There are so many events that come to mind...but you can also design just one. 

I remember long ago (I'm not telling you how long!), you could get custom t-shirts, but you were very limited on the lettering and pictures.  Today, you can basically design you own shirts!  Bluecotton.com makes it pretty easy too.  You just pick the kind of shirt you want and you can add shapes and words with just a click!  You can even upload your own pictures and put them on shirts.  (Great Father's Day gift!!!)
