Bookmarks can easily be created with removed, postmarked stamps. When you receive letters in the mail (or packages), simply remove the stamps. Fill a sink or bowl with warm water and a drop of liquid dish detergent, place them into the water and wait until the stamp removes itself. Typically, the stamps will float to the top of the water. Remove and let dry completely. To dry them, be sure to place them with front side down, so they will not stick to the surface you are drying them on.
For the bookmark above, I used a cut piece of cardstock and a plastic bookmark sleeve. You can use any flat recycled (thin) materials to make your bookmarks. Attach them with white glue, glue stick or decoupage medium. Allow the stamps to completely dry before using or giving as a gift.
Tassels can be created from leftover embroidery floss or simply tie on leftover string, ribbon or yarn. There are no rules to make these, simply have fun. You could even make one of these cutting a piece of Christmas card, or greeting card, and attaching coordinating stamps to the back side of the card. Punch a hole at the top with a one-hole punch.
Have fun Recycling!
