When shopping for embellishments, don't limit yourself to the scrapbook aisle. You can go to the party favor aisle (children's birthday party gift bag items), the baby aisle (mini plastic clothes pins, plastic diaper pins, etc), wedding aisle (tulle, ribbon, rings, acid free place cards, etc), the floral aisle (glass beads for page pebbles, flower stalks that can be separated and used, etc) and mosaics aisle (plastic or glass mosaic pieces that can be added as page pebbles).
And, your possibilities aren't limited to just your LSS, craft store, or Wal-mart either. Don't forget about your hardware store or home improvement store. You can get metal screening and meshing there, washers, grommets, etc. You are only limited by your imagination.
