The time to send out cards for the holidays is here. Make them special by crafting your own. Here are three ideas for you to make your cards extra special. Woodblock prints look great and it’s surprisingly easy to make a lot of them. Aluminum relief cards look like they have been formed out of metal, but they are easy to make for those who can be patient enough to let glue dry. Finally, if you want to send a message made out of light, you can make long exposure photographs and write your message in the air.
