While Gavin was napping this afternoon I stumbled up this website
Here they have t-shirts for just about everything. In the search bar, type in what you support, whether it's cystic fibrosis, autism, cerebral palsy etc. they have shirts for just about every disease & disability. Does it raise money for you cause, no but wearing a t-shirt will get the word out about your cause. And we all know that awareness is a huge step in fighting for a cure!
They have sizes for babies, toddlers, kids and adults! And the prices are pretty reasonable, just thought I would share!
