Here is a quick, and I mean quick, little valentine project. All you need are some recycled safety envelopes and a little baker’s twine, yarn or string. Cut out double-sided heart shapes, fold at the top, place them on your twine and glue the two sides of the heart together. BAM!! You’re done. Use them to hang in a doorway or window, or wrap them around a special gift, or tuck them into a valentine card.
