Plastic Bottle Pendant

Water bottle crafts are eco-friendly and so much fun to make. Dip into your recycle bin and create your a Plastic Bottle Pendant from Heidi Borchers that you can wear with any outfit. Choose colorful alcohol inks to bring your piece to life and add dimension.

Plastic Bottle Pendant


  • Cool2Cast
  • Plastic zip bag
  • Water and measuring cups
  • Non-stick surface
  • Water bottles – with ridged sides
  • Craft knife
  • Scissors
  • Hole punch
  • Cardboard scrap
  • Eyelet(s), jump ring(s) and jewelry pliers
  • Alcohol inks – colors of your choice
  • Gloves
  • Rubbing alcohol in spray bottle
  • Aleene’s Original Tacky Glue
  • Optional: Aleene’s Spray Acrylic Sealer -  Gloss


  1. Use craft knife to punch into the side of water bottle. Use scissors to cut various pendant shapes.
  2. Punch hole at top of pendant. (This will be where you insert the eyelet.)
  3. Place pendant shapes on non-stick surface with curved side up. (You can pour pendants either way but it is easier to start with curved side up.)
  4. Mix a small batch of Cool2Cast according to label directions. (Remember you have to use up all the Cool2Cast that you mix because you cannot save the mixed batches.) You will want your Cool2Cast the consistency of thick pancake batter. After you first mix and shake your batch, open the zip top and check the batch to see how thick it is. If it is too runny, it will run off the water bottle. Re-check every 5 minutes until the batch is the right consistency. (You can also watch the video to see the consistency.)
  5. Snip a small corner of the zip bag – this is what you will use as the pouring spout. Hold bag over the pendant piece and gently pour Cool2Cast over the pendant. Cover entire piece.  Use a scrap of cardboard (or palette knife or craft knife) to lift the piece off the non-stick surface and move it to a clean area. This will help to clean up the poured edges.
  6. Leave piece(s) undisturbed overnight to dry completely.
  7. When the piece is dry, pull the water bottle away from the Cool2Cast but save this piece because you will be gluing it back in place.
  8. Put on gloves, Apply alcohol ink liberally on both sides in desired colors and patterns. If desired, spray surface with rubbing alcohol to help colors blend more. Let dry.
  9. Apply a thin coat of glue to the back of the water bottle piece and glue it back in place over the Cool2Cast. Let dry. Optional: if you prefer to leave the water bottle piece off the pendant, you can spray the front and back of the Cool2Cast with gloss sealer.
  10. Insert eyelet into hole in plastic pendant and glue in place. Let dry. Add jump ring to eyelet hole. String pendants as desired.
