My friend Janet sent me some pictures of two cards she made during a crafty day that she held Sunday with some friends. She found the instructions on YouTube.
Fun Fold Card
The video below was posted by tomshackj. Note: Instead of the video scoring dimensions, score your folds at 5-1/2" and 3-1/4" so the card will be completely centered.
Diamond Fold Card
The video below was posted by Chris Walker. Her blog is called Text, Dies & Double-Sided Tape and you can find lots of card making inspiration there. She supplies a free, downloadable Word document with the instructions for her Diamond Fold Card Project on her blog.
