Cauldron Place Card Holders

These little cauldron place card holders are a fun Halloween decoration for spooky dinner parties.  They are made from polymer clay and can be customized with different colors of potion.  The cauldrons themselves can be made from a variety of metallic colors to match your theme.

To make each place card holder, you'll need:
  • Aluminum foil (about 4" off the roll)
  • Stiff wire -- I used 10 gauge copper wire but you can use floral stems
  • Needlenose Pliers
  • Wire Cutters
  • Polymer Clay in the color of your choice to be the "potion" -- about 1/8th of a 2oz block
  • Black Polymer Clay -- about 1/4th of a 2oz block
  • A thin pointy object such as the end of a small craft paint brush
  • A thin, smooth rod, such as a screwdriver, to wrap the wire around when creating your card holding loop

First, make a foil core.  It's possible to use polymer clay to serve as the core but I didn't want to waste clay.  Create the core by simply wadding up your foil into a ball.  Don't press it too tightly.  You want the ball to be about 1.25" across.  Then press the ball down on two sides to create a flattened disk.  The disk should be about 1/2" thick.  Poke a hole in the center of your disk.  You can use the end of your wire to do this but I used a toothpick.


Cut a 6" length of wire.  Using pliers, make a rough loop in one end and then bend the wire at a 90 degree angle to the loop.  This way, when the loop is laying flat on a surface, the wire is sticking straight up in the air.

Pull the straight length of wire through the hole so the loop acts as a stopper at the other end.

Roll your colored clay, about 1/8th of a 2 oz block of clay, into a ball.  Flatten it until it is about the diameter of your foil disk.  Pierce through the center of this clay with the end of the wire and pull the disk down over the foil. Smooth the edges of the clay down over the sides of the foil.
(It is possible to make the loops in the wire that will hold the card in this step instead of later.  See the last step for details.)

Bake this at the temperature and time specified by your brand of polymer clay, in a glass baking pan.  I line the bottom of my baking pan with paper.

Once this foil and clay creation has cooled, it's time to form the cauldron around it. Gather about 1/4th of a 2oz block of clay and roll it in your hands until it's soft and pliable.  Pinch off enough to make about a 1/2" ball of clay and set this aside.

Form the larger clump of clay into a ball and flatten it into a disk until it's about twice as wide as the foil disk.  Place the foil disk in the center and work it up and around the foil piece, as shown.  Pull the clay around the top and smooth the top edge.  Then press the clay to taper away from this edge and create the flared top of the cauldron.


Divide the rest of the remaining black clay into four equal sections.  Set one aside.  Roll each of the other three sections into a ball.  Place the balls on the bottom of the cauldron, evenly spaced, to serve as legs.  Then press the cauldron down, pushing in on the already hardened colored "potion" in the center of the cauldron, until it's level and the legs are pressed on well.

To create the handles on the sides, divide the remaining clay in two.  Roll each section into a ball and flatten slightly.  Press the end of a paintbrush or chopsitck into the the center of one disk and then, keeping the point in the clay, place it against the side of the cauldron and press the point in slightly to secure the handles.  Pull away the point.  Repeat to create a handle for the other side.

Recessed Hangers for Poured Plaster Pieces

This is a simple method for creating a recessed mounting system for flat-back plaster objects.  The resultant hangers will allow the objects to hang flat against a wall.  Hanging wire is embedded in modeling clay before being pressed into wet plaster.  The clay is later removed and the result is a cavity with a recessed hanging wire to accommodate nails or other hanging assemblies.

I used this technique in my World of Warcraft Hearthstone Plaque and Chalkboard Conversation Heart.

You Need:
Modeling Clay*
Wire for Hanging (non-rusting like copper or aluminum; sized to hold the weight of your finished product)
Plaster mold
Plaster - mixed as directed

*This MUST be traditional modeling clay or Plasticine, not Play-Doh or similar play clays.  Play-Doh is water-based.  It tends to absorb moisture out of the plaster and turn into a big, gooey mess that can't be pulled out of the cavity easily.

Sizing
Decide how deep you want the cavity to be.  You probably don't want the cavity to be any deeper than half the full depth of the object.

Determine how wide you want the cavity to be.  It should be fairly wide, allowing you to center the object when it hangs.  This is especially important with unsymmetrical objects because you won't know where the center of gravity might be.  Add an extra inch or more (depending on the size of your object) to this width and cut your wire to length.

The cavity should also be sufficiently tall, so the object hangs off the wire, not the top of the cavity.

Create The Hanger
 
Next you simply need to embed your wire in clay that fits the dimensions of the cavity in which the wire will be placed.  Make sure your wire ends are poking out.  I like to curl or bend these so the plaster "grips" it better.

Installation
Pour your plaster piece, tap out air bubble and immediately place this assembly in the back, roughly centered vertically and above the center horizontally in the thickest section you can find. Make sure you embed the wire edges in the plaster.
  

Once the object has set, use toothpicks or other tools to dig out the clay. Finish the piece as you'd like and hang from your wire.
