A simple way to bring past donors back (along with more than a few new veins) to an upcoming blood drive is by sending out custom-designed postcards that invite them to share what they have with those who need it. Choose from our library of professionally-crafted blood drive postcard templates, then take advantage of the tools in our online editor to make your postcard your own. Print a few boxes at your favorite local shop or order a stack from us. You can also share your postcards in PDF form on all social media platforms, so nothing can hold you back!
