"Turn socks into mini-canvases to create and send 'footnotes'," suggests McCarthy. "Use the design given or modify to support your school, express your patriotism or create a personal 'footnote' for a special person. The special messages can hide in shoes or peek proudly through sandals." As is so often the case, the colour possibilities are endless, and you can make your message as bright or subtle as the recipient's character. Only the message shown is charted; if you want to compose your own, you get to make up your own letters.
