Mixed media Halloween art

I made this project for the Powertex UK Design Team using the Secret Art Box. The October 2019 subscription box was packed full of Halloween themed supplies. Everything I needed to make some dark mixed media was included. Pick up similar embellishments and pieces from craft stores or take a look on Powertex UK. See the supplies list below if you’d like to create something in this style.

The original step by step guide to this project was published on the Powertex UK Mixed Media Magazine. Watch the time-lapse video of me creating it, and read the tips for creating your own.

Supplies and Materials

  • Powertex Universal Medium in Black
  • MDF square base (Powertex UK)
  • Easy Structure and Bister optional
  • Corrugated card
  • Loose weave fabric
  • MDF shapes with a halloween theme
  • Medium 3d texture balls and Powercotton threads
  • Plaster skull
  • Easy Varnish
  • Powercolor pigments in Lilac, Blue and White

Why do I use Powertex Universal Medium?

Powertex Universal Medium is a paint, glue and fabric hardener which makes it perfect for creating mixed media art and crafts. All the pieces in this project have been coated and layered with Black Powertex and speed dried with a hairdryer before adding layers of colour.

The key to successful mixed media projects like these is to use a variety of textures. Being generous with your pieces helps too. Create foundation layers to build dimension and create background texture. Corrugated card is brilliant but any packaging or tissue paper will give great textures too.

Add a focal point

To finish, create a focal point. This could be something large or just different to the pieces around it. In this project I added a plaster skull on top of an mdf spider web. Use small textures at the end like the 3d balls and Powercotton threads to add details. Watch how I put the layers together in this time-lapse video.

Add colour with Powertex Powercolor pigments

Using powder pigments like Powercolor can seem strange if you’re used to paint or inks but these pigments are potent and versatile. For this project, damp your brush with Easy Varnish and dip into the powder pigment to mix this into a paint on a craft mat.

A dry-ish paint is good for highlighting textures in this project. Use a flat brush and drag it over your project. Build up colour slowly and if you don’t like what you’ve done, simply paint over it with another layer of colour.

I hope you’ve found these tips helpful for making your own mixed media projects. Share you own Halloween Powertex projects in my Facebook group.
