vintage paper trees made from a half circle. would be so cute on canvas art, as garland or on packages or cards. Picture only but would be easy, just fold half circle back and forth on itself. Add ribbon or more paper for trunk.
Make a flag line from your scrap papers, cutting each one like a small banner. Secure the end of the line with buttons. The card front can be several layers as seen here, or layers and colors of your choice. This one is a colorful handmade birthday card.
This would be a neat Valentine's Day gift. if I could bring myself to punch holes in a book. Maybe I could use old magazines instead. Punch a hole in the shape of a heart into an old book and arrange them into a frame for a decoration.
