On the morning of Valentine's Day, we made cards for people using card stock and wrapping paper samples. My mother got the old wrapping paper sample books from a paper company for free. Each sample is about 6" x 14" so there is enough pattern showing to give much material for collage cards.
Since the cards turned out so cute, I would like to take credit for this idea, but mother hand delivered the sample books and the idea. All we did was to think about what pictures would make the receiver smile, then cut and paste. I printed the card stock and cut it to fit the envelopes before we got started. Both children thought their cards looked better than purchased cards. We had so much fun!!
Check local paper companies for cast off wrapping paper samples and make your own cards.
