Draw a 6 inch by 1.5 inch rectangle on a piece of paper or cardstock. (Or whatever size you'd like your bookmark to be)
Cut out the rectangle.
Place the rectangle on top of the transparency film. Carefully hold the rectangle in place and cut around it to make the transparent bookmark.
Step 3: Add Mod Podge and pressed flowers
Working in 2 inch sections, brush a thin layer of Mod Podge onto the transparency film rectangle.
Place pressed flowers and dried greenery onto the Mod Podge.
Apply another thin layer of Mod Podge over top of the flowers.
Continue this pattern, placing flowers until the whole bookmark is covered.
Now seal the whole bookmark by brushing another thin layer of Mod Podge over the entire rectangle.Wait 30 minutes, and brush a second coat of Mod Podge onto the bookmark. Wait another 30 minutes, and add a third coat.
Step 4: Tie a ribbon to the bookmark
Once the bookmark is dry (about 1 to 1.5 hours), use a single hole punch to punch a hole in the top center of the bookmark.
Cut a 5 inch piece of thin ribbon.
Feed the ribbon through the hole and tie a knot in it close to the bookmark.
