Under The Sea Polymer Clay Medallion Tutorial

Under The Sea Polymer Clay Medallion

This Under the Sea polymer clay medallion is a great excuse to have some fun and mess around with Christi Friesen's fabulous Swellegant range.

This is a very unpredicable medium, but I've been testing it out on various projects for quite a while now, so hopefully, in this project I will be able to give you some pointers to bring it a little more under control and we will end up with a beautiful rusted polymer clay medallion.

Have fun!

How to Make My Under the Sea Polymer Clay Medallion Step by Step

Making the Medallion
  • To start with, you will need a sheet of Premo rolled out on the thickest setting of your pasta machine.
  • Dust each side with cornstarch.
  • Texture half the clay with your chosen texture stamp - I am using my Sand stamp from JessamaDesign.
  • Texture the other half with your chosen image stamp - I am using my Nautilus stamp from JessamaDesign.
  • Cut out the nautilus using a circle cutter.
  • Lay the same cutter over your textured clay and roughly trim 1cm around the outside with a frilly outline.
  • Lay your Nautilus in the middle and trim until you are happy with the size.
  • Use the same cutter, place over the Nautilus and cut a circle from the textured clay.
  • Apply Swellegant prep to both pieces using a brush.
  • When dry use a piece of coarse sandpaper to tap along the edges of your donut to roughen the edges up a bit.
  • Lift up your pieces gently with a tissue blade, and lay on two separate pieces of deli paper.
  • Add Swellegant to your Nautilus - I am using Bronze, Copper and Brass. Add in thin coats. Start with the bronze leaving a few white patches. Fill in the gaps with copper. Add a touch of brass in the last open space, and add some over the other areas.
  • Leave to dry. Add a second coat and a third if necessary.
  • Add Swellegant to your textured donut. I am adding Iron.
  • Leave to dry. Add a second coat and a third if necessary.
  • While your second or third coat is still wet on your Nautilus add your Gold-Green Verdigris Patina. I am just dropping it on with a wet wipe, and dabbing. Cover with the wet wipe and leave for an hour.
  • While your second or third coat is still wet on your textured Donut add your Rust Patina. I am just dropping it on with a tissue, and dabbing. Cover with the soaked tissue and leave for an hour.
  • Remove the coverings and allow to dry for 20 minutes more.
  • Highlight the Nautilus with Swellegant Brass.
  • Fit your two pieces together.
  • Place a textured piece of clay on the back and trim using a craft knife.
  • Use coarse sandpaper to press lightly around the edges.
  • Bake for an hour at your brand's recommended temperature.
Making the Copper Spirals
  • Make three copper wire spirals.
  • Texture both sides using a ball hammer.
  • Buff them up using a polishing cloth.
  • Add a small amount of Tiffany Rust into a cup and drop your spirals in. Leave for about an hour to antique them.
  • Remove them, and dry them. Return the leftover Patina to its pot and rehammer the spirals.
Finishing off the Polymer Clay Medallion
  • Cover any white areas with brown paint to tidy the edges.
  • Cover the back with Swellegant prep and allow to dry.
  • Cover with a full layer of Swellegant Copper. Make sure to do the sides too. Allow to dry and then add a second coat.
  • While the second coat is still wet, dab on a few spots of iron.
  • Place on a tissue and pour a small amount of Tiffany rust onto the back. Move around with a skewer.
  • Leave for half an hour or until completely dry.
  • Re-highlight the Nautilus with some more brass.
  • Seal the front and back with Swellegant Sealant.
  • Bake for 15 minutes.
  • You can apply a light layer of Renaissance wax and buff if you like.
Finishing off the Polymer Clay Medallion Necklace
  • Use a pin drill to drill three holes along the bottom of your medallion.
  • Put a copper jumpring through each hole.
  • Cut three pieces of copper chain, one longer than the other two. Attach to the jumprings with the longest piece in the middle.
  • Add a wire spiral to the bottom of each chain using a jumpring.
  • If you have some, attach some open shells randomly on your chain pieces.
  • Use your pin drill to drill a hole through the top of the medallion opposite the middle bottom hole.
  • Put a jumpring through the hole and attach a bail.
  • Cut three pieces of suede in colors of your choice.
  • Place all three pieces in a cord end and crimp together.
  • Slip the cord ends onto the loop of an eyepin and cover with a cone.
  • Create a loop with the excess wire.
  • Plait your cords and pass them through your bail.
  • Finish off the other end in the same way.
  • Use jumprings to attach your clasp.
And that's how to make my Under the Sea Polymer Clay Medallion Necklace! I hope you enjoyed that tutorial.
