How to Make a Vinyl Doll Mold
Moulding a vinyl doll allows it to be recreated in matching detail. (doll image by Ramona smiers from

Creating objects out of vinyl yields a product that is strong and durable and also easy to clean should it become dirty. Due to these positive characteristics, vinyl is used to create a wide range of products, including vinyl dolls. In order to create multiple exact copies of a doll, a mould of the doll is taken, which can then be used to pour copies. Using acrylic and urethane mix, you can create your own mould of your vinyl doll.

Skill level:

Things you need

  • Clear acrylic sheet
  • Saw
  • Hot glue
  • Clay
  • Vinyl doll
  • Pencil with eraser
  • Rice
  • Measuring cup
  • Urethane mix
  • Mixing cup and stick
  • Putty knife

  1. 1

    Cut four pieces of clear acrylic sheet large enough to build a rectangular box that is taller than the doll is wide and can fit around the doll. Secure the rectangle with hot glue.

  2. 2

    Cut a piece of clear acrylic sheet several inches larger than the rectangle and secure the rectangle atop it with a light application of hot glue. Use just enough hot glue for a watertight seal, as you will need to pry this section apart.

  3. 3

    Fill the bottom half of the box with nondrying clay, ensuring that the clay fully covers the perimeter of the rectangle.

  4. 4

    Press the vinyl doll into the clay with a piece of the doll touching one of the edges of the box. Feet are usually the best part for placing on the edge.

  5. 5

    Press the eraser of a pencil 1/4 inch into the clay at all four corners. This will create keys for aligning your mould.

  6. 6

    Pour rice into the mould until it completely covers the doll, and then pour the rice into a measuring cup to determine how much urethane is needed for the mould.

  7. 7

    Spray mould release into the box.

  8. 8

    Mix your urethane according to the packaging on the urethane product you have purchased, as recipes vary by brand, and then pour the urethane into the mould. Do not pour the urethane directly on the doll; instead, pour it into a corner and let it flow over the doll.

  9. 9

    Pry the bottom section off of the rectangle with a putty knife after 24 hours, and then remove the clay from the rectangle.

  10. 10

    Repeat the rice measuring and subsequent urethane mixing and pouring, with the first urethane pouring serving as the bottom of the mould, then leave to dry for 24 hours. This creates the second half of the urethane mould, which is then held together with the first to create a hollow cavity in the shape of the doll.

  11. 11

    Pry the pieces of clear acrylic sheet apart, if needed, to release the mould from the box, and then open the mould and take out the doll.
