I save old calendars and magazines and use the pictures I like from them to make cards and envelopes. It's easy to make an envelope -- just take and old envelope apart to use as a template. Trace it on the page you like, cut around the line, fold and glue. I use these cards and envelopes for party invitations or thank you notes. I have not bought thank you cards since learning this trick, so I've saved a bundle and reuse our precious resources! Have fun with recycling!
