TErrific idea....That's an ingriguing idea.....You would have to somewho keep track of where it was..

..be sure to place a cardboard between the layers of the shirt.

It would be something like the recent campaign by the ACS of having persons in a community come to the cancer center and sign a banner that was sent to DC.

If you can't send it around, you could write the names yourself, or have a print shop do it for you.....perhaps at a mall.

You are a dear to think of this. If you do it yourself, you could use paint markers. (Here is a dear, personal story: When my mother turned 75, the entire family got together for a party, and each member signed a black sweat shirt as her birthday gift, since nothing was as important to her as her family. She loved that shirt. When she died (of natural causes) the next year, we chose to bury her in that shirt....to surround her one last time and forever with the names of those she treasured so.)
