I've made a tag for this theme today at Tando Creative.
I used a media board painted with gesso and when dry scraped white modeling paste through a stencil.
These pieces I took from a bits box which were already painted - leftovers from previous projects.
I also grabbed these from another bits box of Tando leftovers to add to the design. As you can see these were not painted or sealed so I started by gluing these to the media board ...
.... and when dry I gave it all a coat of gesso.
Next I sprayed some water based and DecoArt white mister over the surface, dried it and repeated again to give me my base colours ...
.... and then dribbled some watery media acrylic paints, ....
.... sanded and inked the edges of the board and finished with some splatters of titanium white.
Because the sprays I used were water based they created some lovely mottled effects together when I spritzed them and when I repeated the layer.
Media board, chipboards.
